Machine Signals

The following shall give an overview of the electronic interfaces at the machine to specific signals, e.g. for data acquisition.

Timing system

scuxl0319

SCUXL0319

The timing receiver scuxl0319 is located in electronics hutch (TH2.033), at the top of rack EX3. Besides the two B1/B2 channels on the SCU card, it contains two function generator cards type FG 900.740 with 8 digital outputs. The B1/B2 channels can be freely reprogrammed to any White Rabbit event, while the function generator cards contain a pre-defined assignment to specific events.
Channel type Function
B1   Programmable through Genesys
B2   Programmable through Genesys
FG1-1 level (CRYRING_RING:) CMD_BEAM_ON right CMD_BEAM_OFF
FG1-2 level (CRYRING_RING:) CMD_EBEAM_ON right CMD_EBEAM_OFF
FG1-3 level (CRYRING_RING:) CMD_TARGET_ON right CMD_TARGET_OFF
FG1-4 level (CRYRING_RING:) CMD_EXP_DAQ_START right CMD_EXP_DAQ_STOP
FG1-5   - not used -
FG1-6   - not used -
FG1-7   - not used -
FG1-8   - not used -
FG2-1 pulse CMD_TARGET_ON
FG2-2 pulse CMD_TARGET_OFF
FG2-3 pulse CMD_EXP_DAQ_START
FG2-4 pulse CMD_EXP_DAQ_STOP
FG2-5 pulse CMD_EXP_DRIVE_IN
FG2-6 pulse CMD_EXP_DRIVE_OUT
FG2-7 pulse CMD_INJ_KICKER_START
FG2-8 pulse CMD_EXTR_KICKER_START
Signals types are TTL (+5V) and if specified as level they are Hi for the inter-event duration of the corresponding events listed in the Function column of above table. If the type is specified as pulse the duration is 1 us.

scuxl0006

A second timing receiver is scuxl0006 and is located inside the HV cage of the electron cooler and also running the Genesys class. There are only two channels available, the B1/B2 channels on the SCU card. Their assignment is as follows:
Channel Level Function
B1 TTL Genesys: Hi-Level from CMD_EXP_DAQ_START arrowright CMD_EXP_DAQ_STOP
B2 TTL Genesys: TBA

Beam diagnostics

IMG_4417.jpgA patch panel at the top of rack EX3 in the electronics hutch (TH2.033) is interfacing with signals from the BeamDiagnostics electronics room (connectors: BNC-50Ω) The assignment of the channels is semi-permanent and as follows:
