Starting from Scratch

If the experiments (bnmr/bnqr) have not been running previously (e.g. at the start of the beam period) you will need to start from scratch. Usually you will want to run both experiments during the beam period.

In the counting room, the linux boxes isdaq01 and isdaq06 are used to run the bnmr and bnqr experiments. They are located side-by-side and each have 2 screens. Note that the DAQ system for both experiments actually runs on isdaq01. The second box isdaq06 is used just to display the second experiment. To start one of the experiments while logged on to isdaq06, one must first ssh to isdaq01 as explained below. Both isdaq01 and isdaq06 are part of a NIS cluster (the master is isdaq00 located in the computer room). Users access the same user and data disks from either machine.

In the following example, bnmr experiment is run on isdaq01 console and bnqr on isdaq06 console. It doesn't matter which experiment runs on which console. If only one of bnmr/bnqr is to be run, start it on isdaq01.

If any other user is already logged on, log them out first.

For bnmr experiment:

1. Log onto isdaq01 as user bnmr
2. Start a web browser (firefox)
3. Start an xterm and type scripts kill-all followed by start-all to start all DAQ software components
4. Point the web browser to the bnmr experiment status page ( https://isdaq01:8443 ) & enter username and password
5. Open the EPICS page on another desktop if desired.

For bnqr experiment:

1. Log onto isdaq06 as user bnqr
2. Bring up a web browser (firefox)
3. Start an xterm
   1. ssh bnqr@isdaq01
   2. Type kill-all followed by start-all to start all DAQ software components
4. Point the web browser to the bnqr experiment status page ( https://isdaq01:8444 ) & enter username and password
5. Open the EPICS page on another desktop if desired.

On the EPICS windows, make sure that BNMR has Access.
