Event	Description	Source
$A0	Any Linac Beam	Pulse Shifter Beam Status
$A1	LLRF Trigger	LLRFTR, Timer 601:A3
$A2	Fast Time Plot Event (TClk $02)	Timer PAL Output
$A3	HE Quad Sample Time	QSMAPL, Timer 601:A2
$A4	HE Quad Power Supply Trigger	QTRIGX, Timer 601:B0
$A5	Linac T-Data	HEP/NTF TData Switch Module (LEI-RR2-10)
$A6	Klystron Node µP Start	MPSTRT, Timer 601:A1
$A7	Klystron 15 Hz Charge	CHARGE, Timer 601:A0
$A8	none	none
$A9	Fake Event (Node 610 only)	Fake Standby Event for JAVA
$AA	HEP $52 or Linac Studies $0A or MTA Beam $03	EVAAD, Timer 601:180
$AB	PreAcc Pulse Shifter	PreAcc Pulse Shifter
$AC	Debuncher Klystron System Delay	KDDLY, Timer 601:B2
$AD	Conditioned Beam Event	Hardware Module in Node 611
$AE	Transition Klystron System Delay	K0VDLY, Timer 601:B1
$AF	Booster Reset (TClk $0C)	TClk from CommRack (Fiber)

Notes:

Event $A0 is generated by beam enable/pulse shifter beam status output (50 µs delay).
Event $AC has jitter problems when 720 Hz event is enabled.
Debuncher is using $AE for its reference.
Event $AD is armed by event $AA, delayed 100 µs, and triggered by event $AF.
(to remove HEP/Studies clock event jitter relative to beam)
