1 DESCRIPTION
The one-wide CAMAC 334 module is uniquely associated with
protection of the CDF SVX detector from damaging radiation by
facilitating the generation of an abort request to the
Tevatron Abort System. A pulsed signal, representative of
radiation dose to the detector, is integrated over short,
medium, and long intervals (SI, MI, & LI). Each interval has
programmable alarm and trip levels. Pulse accumulation to the
alarm or trip level for any of the intervals results in module
LAM assertion. Pulse accumulation to the trip level for any
of the intervals may result in the fall of a permit to the
Tevatron Abort System.
The intervals are defined by beam revolutions in the
Tevatron as indicated by TVBS revolution event $AA. The short
interval is set at 10 turns, the long interval at 10,000
turns, and the medium interval at 50, 100, or 200 turns. The
medium interval is set by monitorable jumpers.
The pulse count input is direct to the short integrator,
and has prescale capability for the medium and long
integrators. A prescale of 1 or 2, selectable by a monitored
jumper, is available for the medium integrator. The pulse
prescale for the long integrator is programmable from 10 to
150 in decade steps. The front panel pulse count input is NIM
convention. An alternative TTL compatible pulse count input
is available at the rear of the module.
Integrated values are latched before each of the three
integrators are reset. These latched values are directly
readable and are also loaded into 2K to 16K deep FIFOs. TCLK
events, as well as CAMAC codes, control the stop and start of
the FIFO recording process. FIFOs will stop loading
approximately 10 msec after receipt of TCLK Event $47, which
signifies the fall of the Tevatron Permit Loop. TCLK $48,
which resets the Tevatron Abort Loop, will clear latched
trips. The FIFOs will start recording after TCLK Events $58,
$5B, or $5C which usually signify injection of beam into the
Tevatron. These events also reset and hold off alarms and
trips for approximately 5 milliseconds.

3 CAMAC 334 MODULE - I/O ASSIGNMENTS
Rather than a standard 36 position edge connector in the
I/O space, the CAMAC 334 has five directly mounted Lemo
connectors that are accessible from the rear. Their
assignment from top to bottom is as follows:
TCLK Input
TCLK Output
TVBS Input
Pulse Input (TTL)
Permit Output
4 CAMAC 334 MODULE - FRONT PANEL
The CAMAC 334 module has the following front
panel features:
N led: Red (stretched)
LAM led: Red
Enabled led: Yellow (Module may effect Trip when on.)
Permit Out Lemo: With Green & Red leds (Permit/Trip)
LI leds: Red (Trip), Yellow (Alarm), & Green (OK)
MI leds: Red (Trip), Yellow (Alarm), & Green (OK)
SI leds: Red (Trip), Yellow (Alarm), & Green (OK)
Count Input Lemo (NIM): With Red led (stretched)
TCLK In & Out Lemos: With Green led ($07 stretched)
TVBS $AA In & Out Lemos: With Yellow led ($AA stretched)
5 SPARES
A supply of CAMAC 334 operational spares is maintained on
the second floor of the Linac Annex and possibly at the
Colliding Detector Facility (CDF).
6 ON-BOARD MODULE OPTIONS
There are on-board options for the Medium Integrator
interval for 50, 100, or 200 turns, and for the Medium
Integrator count prescale of 1 or 2. These options are
determined by the installation of small shorting jumpers.
Reference to the schematic is suggested to determine proper
installation.
There is an option for a rear I/O entry of Count Input.
This input, which is terminated in 51 ohms and TTL compatible,
is or'd with the front panel NIM input. In that these inputs
are always or'd, there is no additional requirement to make
use of this option.
The input pulse width may also be configured to
synchronously gate a ring oscillator, thereby providing
multiple counts for wider than nominal count input signals.
This option is made available by the installation of a
shorting jumper on the module. The frequency of the ring
oscillator is determined by RC components. Reference to the
schematic is again suggested if this option is desired.
The 2K deep FIFOs at locations #23, #40, and #61 may be
substituted with 4K, 8K, or 16K deep devices as applications
may warrant.
The checking of all options and PAL designators before
replacement of the module is advised.
