The process of setting up the mobile rack is essentially the same process as tearing it down in reverse. Note that these instructions operate under the assumption that the controls signal routing infrastructure is in such a state that plugging devices into IO panels will just "work". In practice, routing gets mixed up and some patches may not work as expected. If things aren't working right, check with your controls doctor.
- Connect the copper grounding cable to the bottom of the rack.
- Below the detector stand is a patch panel for data fibers, RJ45 ethernet cables, BNC triggers, and gauge power and ion current lines. Connect the ethernet cables from the mobile rack to the RJ45 points on the patch panel. Any points – it doesn't matter. The data fibers from the CSPAD concentrator, however, must go to the corresponding fiber patch points with matching labels (eg. RC0, RC1, EVR). In order to operate CSPAD140k detectors, the detector PDU requires two BNC triggers. Connect the "DAQ-Trig In" point on the PDU to the patch point labeled "DAQ" and the "Run-Trig In" PDU point to "CNTRL" on the patch panel. On the CSPAD Concetrator, the "Trig In" is used to trigger the large CSPAD2.3M in the detector chamber. Some BNC connectors on the detector station patch panels are labeled to indicate which EVR channel it is propagating. The CSPAD trigger needs to be connected to the BNC point that matches the EVR channel designated to the CSPAD in the CXI DAQ configuration file (
/reg/g/pcds/dist/pds/cxi/scripts/{cxi_0.cnf,cxi_1.cnf}). - Connect the motor cables to the detector stand IO panel. Use the CAPTAR tags on the cables to identify which junction points each cable should be connected.
- Carefully connect the CSPAD trunk cable to the detector chamber flange. The pins for these connectors are fragile.
- Plug the power-strips on the side of the rack into 120V outlets on the beamline. If you plug them into other power-strips, Matt Hayes will find out and revoke your privilege to use electricity at SLAC. He can do that.
- Turn everything in the rack on.
- Enable the IOCs using
iocmanager.
