DETAILED TRIGGER TYPE V2 15/2005
(includes Marc Dejardin, Ken Bell and Dave Cockerill comments)
It is a TTC long command (16 bits) that will be written in the DCC header during calibration triggers coming during the orbit gaps. This means ECAL will be running in global mode. During those triggers, the RUN TYPE word will not be available. Of course, we can exercise this word even running in local provided the TTC ci (or equivalent) is available.
This word is composed of:
DCC# (6 bits)
HALF (2 bits):
- FIRST HALF (SM or Dee Quadrant) 01
- SECOND HALF(SM or Dee Quadrant) 10
- FULL SM (SM or Dee Quadrant) 11
TYPE (3 bits):
- LASER 001
- TEST PULSE 010
- PEDEST 011
- LED (for VPT stability) 100
WAVELENGHT (3 bits):
- RED 001
- BLUE 010
- INFRA-RED 011
- GREEN 100
- λ1(LED) 101
- λ2(LED) 110

CYCLE SETTINGS (15 bits):
- for STANDARD LASER SEQUENCE:
- WAVELENGHT (3 bits): 001 red, 010 blue, 011 infra-red,
100 green
- FILTER (set manually): 10 or 20 db (3 bits)

value: 0 – 60 mV for GAIN 16 (x 10)
0 – 500 mV for GAIN 1(x 10)
