AMS Tracker slow control

The JinfT communicates with the various slow control boards through a LeCroy bus. Commands can be directly sent to a selected bus, or the Jinf can execute macro commands to determine the status of all slow control boards: so-called AMSWire "sub-detector specific" commands have been implemented to perform checks and readout of all the slow control devices with simple calls.

  • 2E14 1001: Read the slow-control state, compare with pre-defined values, and give the list of discrepancies. The output format is as follows:
Word # Content
0 Provided by mainframe
1 Provided by mainframe
2 Provided by mainframe
3 Actel mask
4 Number n of discrepancies
5 Discr. #1 (var. name)
6 Discr. #1 (var. content)
... ...
4+(2n-1) Discr. #n (var. name)
4+2n Discr. #n (var. content)

For the discrepancies, the variable content is the actual setting, the one seen by the Jinf when reading out the slow control devices.

  • 2E14 1012: After having executed a 2E14 1001 command, you can also get the list of currents and voltages read out from the Jinf: 2E14 1012. Please note that the output will have a valid meaning only if you have previously executed a 2E14 1001 command. The output format is as follows:

21 Voltage of LR 1 Cold, TBS 15 Power group 3 (C)
19 Voltage of LR0 Cold, TBS 15 Power group 2 (C)
2 Voltage of LR0 Cold, TBS 5 Power group 0 (C)
18 Voltage of LR0 Hot, TBS 15 Power group 2 (H)
1 Voltage of LR0 Hot, TBS 5 Power group 0 (H)
4 Voltage of LR1 Cold, TBS 5 Power group 1 (C)
20 Voltage of LR1 Hot, TBS 15 Power group 3 (H)
3 Voltage of LR1 Hot, TBS 5 Power group 1 (H)

The ADC to voltage and current value is done as follows:

  1. Voltage conversion (in V): V=2+(ADC-270.4)/41.45
  2. Current conversion (in uA): I=(a - 0.0735*ADC) constant 'a' is actually specific to every ADC channel. The following link gives you the parameter list.
