All Versions

There are a total of seven PALs on the 279 module. Source files 27905A.ABL , 27912A.ABL , 27936A.ABL are common to all versions. Source file 27921A.ABL is anticipated to be common to nearly all versions, exception to which will be specifically noted. This file causes both channels of the 279 to be enabled upon power-up or module clear. The programmable enable/ disable feature is maintained. The three remaining PAL source files are generally unique to each implemented version. Top

Version 8.4 RRBS 8 GeV Protons from RR to MI01-18-998 GeV Protons from RR to Accumulator

This version provides a trigger for the MI30 Kicker PS at the MI-30 Service Building. It also provides a trigger for the RR20 Kicker PS at the MI-20 Service Building. The MI30 kicker is normally used for all transfers of P-Bars and Protons between the Recycler and the Main Injector. The RR20 kicker is normally used to kick P-bars into the Recycler from the Main Injector. The RR20 kicker is also used to kick Protons from the Recycler out to the Main Injector. Installation is made at the request of Chris Jensen.
Channel 0
This channel fires the MI30 and RR20 Kickers as part of the process of transferring Proton bunches from the Recycler to the Main Injector. This transfer is for tune-up of P-Bar injection into Recycler. This channel is always armed and outputs a pulse delayed from RRBS event $A3. For the MI30 kicker, parameter I:K3TDA3 is assigned to the delay value. At MI30, this channel output is wire-ored to five other 279 outputs. For the RR20 kicker, parameter R:K2TDA3 is assigned to the delay value. At MI20, this channel output is wire-ored to three other 279 outputs. See note below.
Channel 1
This channel is always armed and outputs a pulse delayed from RRBS event $A6 which normally accompanies transfer of Proton bunches from the Recycler to the Accumulator for tune- up of stacking transfers. For the MI30 kicker, parameter I:K3TDA6 is assigned to the delay value. At MI-30, this channel output is wire-ored to five other 279 outputs. For the RR20 kicker, parameter R:K2TDA6 is assigned to the delay value. At MI-20, this channel output is wire-ored to three other 279 outputs. See note below.

Version 10.1 TVBS & APTVBS 2-6-91; 12/2/99

These 279 modules provides beam synchronous diagnostic pulses for various systems at C0, MRRF, and for E778 at the F4 Service Building. These modules were installed for Gerry Jackson (MRRF) on 12-18-90, for Mike Harrison (F4) on 1-18-88, and for Jim Zagel to the C0 Service Building. This is a rather generic 279 implementation and other copies may be installed in various locations.
Channel 0
This channel, which is always armed, generates pulses delayed from TVBS event $AA. The delay setting for this channel may range from 0 to 157 clock ticks (1 turn max). The channel is armed upon power up or module clear.
Channel 1
This channel is similar to Channel 0 and also references TVBS event $AA. As of this writing, no names have been assigned to any of the delay channels at MRRF. There is no assigned name for the delay channels at F4 in that the module is installed in a non- ACNET CAMAC crate.

Version 12.3 MIBS Main Injector MI40 Abort Kicker & Cln-Up 11-20-98

This version of the 279 module is associated with the beam synchronous firing of the Main Injector MI40 Proton Abort Kicker at the MI40 service building. In addition to normal aborts, channel 1 can fire the abort immediately before transfer of coalesced beam to the Tevatron. This is done during multi-batch coalescing to get rid of unwanted beam (clean off the tail) which might otherwise quench the Tevatron. Protection has been added to prevent multiple firing pulses within a MI cycle. Both channels may be armed only during the period between the MI reset TCLK event and the "end of beam" event ($26). Once either channel has fired, both channels will be held off (inhibited) until the next MI reset event. Protection has been added to prevent the generation of firing pulses if the Main Injector abort loop is made up for less than 100ms. Firing due to collapse of the BP input occurs only if the BP line has been asserted (permitting) for at least 100 milliseconds. For each slot, the channel 0 and 1 outputs are externally or'd with a BNC tee. One each of these tee'd signals feeds the Thyratron Trigger of one of the two power supplies (N12 feeds PS A, N13 feeds PS B). Both channels are disabled on power up or reset.
Channel 0
This channel, when armed, generates a single pulse delayed from MIBS event $AA. The delay setting for this channel may range from 0 to 65535 MIBS clock ticks. Currently assigned names for this delay channel are shown below. The channel is armed by the high to low transition of the BP signal that is applied to the Ext Trig 0 Input if the BP signal has been up for at least 100 milliseconds. The channel is also armed by TCLK event $2F (the Main Injector Clean-Up Pulse). Delays may range into multi-turns. Requested by Jensen.
Channel 1
This channel, when armed, generates a single pulse delayed from MIBS $7C. Currently assigned names for these delay channels are shown below. Delays may range from 0 to 65535 MIBS clock ticks.

Notes
It is absolutely necessary to connect TCLK to this module. The one-shot on the Ext Trig 0 Input is wired to fire on the falling edge of the applied signal. 10-5 and 37-14 should be wired to 9-10 rather than to 9-12. The Ext Trig 0 Input is wired to the Beam (Link) Permit output signal from the fiber optic Main Injector Abort repeater module located in the MI40 repeater chassis, slot 2. TCLK event $2F is stretched to the necessary 750 nsec by employing the DVALID pin of the TCLK decoder rather than the DECEN pin. Accordingly, wire IC #37-6 to IC #32-6 rather than to #32-8. ET1 of the PAL at location #37 is defined as an output. Pin 2 of IC #9 must be removed from the IC socket. The high side of the one-shot at IC #10 is set to time at about 100 milliseconds and fires when LP goes high. 57-4 and 5 are pulled-up to allow delays longer than a single turn for Chan 0. The 100 ohm resistor in this area should be removed. 1500 pf capacitor to ground should be installed at #41-12 (BS4) to effect a reduction in width of R0 & R1.

This channel, when armed, generates a single pulse delayed from RRBS event $D0. The delay setting for this channel may range from 0 to 65535 RRBS clock ticks. R:K4TDD0 is the currently assigned name for this delay channel. The channel is armed by TCLK $E7, "Dump protons on demand" and reset by TCLK $F5. Requested by Krafczyk and GPJ.

Version 13.2 MIBS C48 Transfer Kicker 1-27-88

This version of the 279 module is provided to control the timing of the MI C48 Extraction Kicker that facilitates the transfer of protons from the Main Ring to the Tevatron. This module is being installed at the request of Jim Lackey. The two channel outputs are normally wire-ored together. Version 21.1 at $E1 N18 controls the Tevatron E17 Injection Kicker which is the other associated kicker element for these transfers. Protection has been added on 1-27-88 to prevent the kicker firing if the TEV abort loop is reset between the injection to and normal extraction of beam from the Main Ring. This is accomplished by storing the state of the TEV abort loop at the occurrence of MIBS $77 which shortly preceeds the injection of first beam into the Main Ring.
Channel 0
This channel, when armed, outputs a pulse delayed from MIBS event $78 which initiates the transfer of protons that are destined for fixed-target physics from the Main Ring to the Tevatron. The channel is armed 100 microseconds after the BP/AIP signal from Tevatron CAMAC Crate $1D is asserted and if BP was asserted at the occurrence of MIBS $77. The channel is not armed when BP/AIP is false. M:C48DFT is the parameter assigned to the delay for this channel. This channel normally operates during during a Main Ring cycle marked by TCLK event $21.
Channel 1
This channel, when armed, outputs a pulse delayed from MIBS event $7C which initiates the transfer of protons that are destined for colliding physics from the Main Ring to the Tevatron. The channel is armed 100 microseconds after the BP/AIP signal from Tevatron CAMAC Crate $1D is asserted and if BP was asserted at the occurrence of MIBS $77. The channel is not armed when BP/AIP is false. M:C48DCP is the parameter assigned to the delay for this channel.

Version 26.2 TVBS Tevatron Proton Abort Kicker 1-30-92

This version of the 279 module is provided to fire the Tevatron Proton Abort Power Supply synchronously with the Tevatron Beam Sync Clock. It is normally active during Fixed Target physics operations and sometimes used to abort 150 GeV protons during set-up of Colliding Physics operations. The module accepts both the state of the Tevatron Abort signal and the Tevatron Clean-Up Pulse (TCLK $4B) as arming conditions for the firing of the supply. This module was provided at the request of George Krafczyk and Jim Lackey. Protection has been added on 1-27-88 to prevent the generation of firing pulses if the abort loop is made up for a short time. Firing due to collapse of the BP input occurs only if the BP line has been asserted (permiting) for at least 100 milliseconds.
Channel 0
This channel, when armed, generates a single pulse delayed from TVBS event $AA. The delay setting for this channel may range from 0 to 65535 TVBS clock ticks. T:B48TRG is the currently assigned name for this delay channel. The channel is armed by the high to low transition of the BP/AIP signal that is applied to the Ext Trig 0 Input if the BP signal has been up for at least 100 milliseconds. The channel is also armed by TCLK event $4B which is the Tevatron Clean-Up Pulse. This channel fires the Tevatron MI40 Kicker which aborts protons from the Tevatron.
Channel 1
This channel, used as a diagnostic trigger, is similar to Channel 0 except that it does not arm on the receipt of TCLK event $4B if the BP/AIP signal is low (inhibiting). T:TDCTRG is the currently assigned name for this delay channel.

Notes
It is absolutely necessary to connect TCLK to this module. The one-shot on the Ext Trig 0 Input is wired to fire on the falling edge of the applied signal. 10-5 should be wired to 9-10 rather than to 9-12. The Ext Trig 0 Input is wired to the BP/AIP output signal from the $1C TSCC. TCLK event $4B is stretched to the necessary 750 nsec by employing the DVALID pin of the TCLK decoder rather than the DECEN pin. Accordingly, wire IC #37-6 to IC #32-6 rather than to #32-8. ET1 of the PAL at location #37 is defined as an output. Pin 2 of IC #9 must be removed from the IC socket. The high side of the one-shot at IC #10 is set to time at about 100 milliseconds and fires when BP goes high. 57-1, 2, 4, and 5 are pulled-up to allow delays longer than a single turn. The 100 ohm resistors in this area should be removed.

Version 42.0 MIBS

This version of the 279 module provides two separate triggers to Accumulator Extraction Kicker. This kicker is used for the extraction of P-Bars from the Accumulator to the Main Ring and for the reverse injection of protons from the Main Ring to the Accumulator. The outputs of this module are normally applied to separate LeCroy 4222 modules for finer delay control. This module was installed at the request of Helen Edwards.
Channel 0
This channel will fire the kicker when 8 Gev protons are being transferred from the Main Ring to the Accumulator. The associated accelerator resets for this operation are TCLK event $16 for the Booster and TCLK event $2D for the Main Ring. This channel will output a pulse delayed from MIBS event $7E. Parameter A:PINJK is assigned to the delay value.
Channel 1
This channel will fire the kicker when a small 53 MHz bunched P-Bar batch on the extraction orbit of the Accumulator is being transferred to the Main Ring. The associated accelerator resets for this operation are TCLK events $91, $9A, $9B, or $9C for the Accumulator (to tag the unstack process for a X, Y, or Z P-Bar bunch) and TCLK event $2A for the Main Ring. This channel will output a pulse delayed from MIBS event $7A. Parameter A:PBEXTK is assigned to the delay value.

Notes
It is not necessary to connect TCLK to this module. This module is not actively being used at the present time but is provided in hopes of replacing the 277 MIBS timer currently used. A final implementation would require two separate LeCroy 4222 modules, one for each channel output to provide finer delays than achievable with the 279. The LeCroy 4222 delays would normally range from 0 to 132 nanoseconds. Note that the LeCroy 4222 presents a fixed delay of 170 nanoseconds for zero programmed delay. The 4222 outputs should be wire-ored before application to the kicker. This module is exactly similar to Version 4.1 which provides triggers to the E48 Kicker in the Main Ring.
