| + | * The OBJ, XFP, and E1 up signals to the MTDC go through the Mesytec MCFD | ||
| + | * Before going to the TACs and TDC, the OBJ and XFP signals are sent to a CANBERRA CFD 454 CFD in data U6 from the data-U6 patch panel (OBJ: patch panel #54, XFP: patch panel #1) | ||
| + | * MTDC: | ||
| + | * The OBJ signal into the MCFD comes from the detector via S3 patch panel #94 (going to the target area) | ||
| + | * The XFP signal into the MCFD module comes from data-U6 patch panel #70, connected to the CANBERRA 454 CFD XFP output | ||
| + | * SpecTcl calculates the ToF by substracting the MTDC time from XFP (MTDC channel 2) or OBJ (MTDC channel 3) to the MTDC time from E1 up (MTDC channel 15) | ||
| + | * The MTDC timing signals do not require external delay adjustments because the matching window is sufficiently wide | ||

| + | * The OBJ output signal from the CANBERRA 454 CFD is delayed with the low-noise delay boxes in data-U6, and sent to the TDC via patch panel #67 | ||
| + | * The XFP output signal from the CANBERRA 454 CFD is delayed with the low-noise delay boxes in data-U6, and sent to the TDC via patch panel #66 | ||
| + | * The TDC start is sent from the ULM trigger module. Since the delay of the S800 trigger may be adjusted during XDT, the stop signals (e.g. from OBJ or XFP) will need to be re-adjusted. | ||

| + | * Examine the timing of each of the selectable listed signals with respect to the “Live Trigger” signal | ||
| + | * There are 4 TDC inspect channels patched to data-U6 that can be assigned using the trigger GUI | ||
| + | * The full range of the TDC is 400 ns | ||
| + | * Set each timing to 200 ns | ||
| + | * TDCs of last 4 listed signals (including XF and object scintillators) are bypassed with cable delays inside the vault and thus their delays cannot be controlled with the GUI | ||
| + | * They can be inspected, however using the GUI | ||
| + | |||
| + | |||
| + | * The TDC delays can only be changed when the run control is stopped; must SAVE settings before starting run control not to overwrite adjustments being made | ||
