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

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	TTL	Genesys: Hi-Level from CMD_EXP_DAQ_START CMD_EXP_DAQ_STOP
B2	TTL	Genesys: TBA

scuxl0006

A second timing receiver is scuxl0006 and is located in cooler HV platform, running genesys class. There are only two channels, the B1/B2 channels on the SCU card.

Channel	Level	Function
B1	TTL	Genesys: Hi-Level from CMD_EXP_DAQ_START CMD_EXP_DAQ_STOP
B2	TTL	Genesys: TBA

Beam diagnostics

A 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:
