DRALS cabling (DR part) |

Green Corner, patch panel to ESR
All signals from/ to ESR TTL 5V.
Signals are GND decoupled with grey boxes! Don't use the signals directly.
[1] New Ramp (NR) / Meas Gate
[2] New Step (NS)
[3] End of Ramp (ER) / COOL
[4] to ESR: Start Measure Trigger
[5] to ESR: Laser Trigger (~ 30 Hz)
[6] MEAS0
[7] MEAS1
[8] VFC
Patch Panel "Green Corner" (DR) <-> "Blue Corner" (Laser)
Signals are neg NIM unless otherwise indicated
(i.e. the two signals from/to the DR Trigger side need to be TTL)
[11] to DR side: Laser Trigger (TTL) => to do => done
[12] from DR side Injection; signal comes from DR DAQ!!! => to do
[13] Meas Gate
[14] VFC
[15] to DR side: Part Det South (Cooler) => to do
[16] to DR side: Part Det North (Gas jet) => to do
[25] COOL
[26] MEAS0
[27] MEAS1
[28] New Step (NS)
[29] SubTrig 1
[30] SubTrig 2
[31] SubTrig 3
[32] SubTrig 4
NACOM 1 => Signals ar ORed as Master Readout Trigger and Counted in DRALS Scaler 9 to 16
[1] COOL => SC Ch9
[2] MEAS0 => SC Ch10
[3] MEAS1
[4] New Step (NS)
[5] SubTrig 1
[6] SubTrig 2
[7] SubTrig 3
[8] SubTrig 4 =Sc Ch16
The Measgate Signal (logic high when in measurement window) is ANDed with 100 kHz clock. The strobed signal is put in DRALS DAQ ( to do). |
