Beginning of Run Checkout

This subsection describes the beginning of run checkout needed for DAQ and trigger.

1.

First ensure that all the crates are powered on. The fastbus, VME, CAMAC, and NIM crates are located in the lower and upper levels of the spectrometer shield huts. They will boot up in a functional state.

2.

You may download a default trigger, following the directions in the trigger chapter. If the hadron momentum changes you may need to set a new delay.

3.

Make sure the HV is on and the values are normal.

4.

Start the xscaler display following the instructions below and check that the rates from detectors are normal.

5.

Startup RunControl (CODA) using the directions below and start a run. With the trigger dowloaded and the HV on, you are taking cosmics data, typically at a rate of 4 Hz. Examine the data using dataspy, dhist, and ESPACE as explained below. Compare the plots and printouts to normal values.
