Introduction

The software package CAMP is used for the slow controls for the bnmr and bnqr experiments.

The CAMP server runs on a MVME162 located in the VME crate. The name of the MVME162 is

• bnmrvw for the bnmr experiment or
• polvw for bnqr experiment

The CAMP system itself is accessed using the CAMP User Interface (CUI). Using the CUI, the user can add instruments to be accessed by the DAQ system during the experiment.

CAMP User Interface

To access the CUI, in an xterm type "camp".

[bnmr@isdaq01 ~]camp

A display similar to Figure 1 will appear.

Figure 1 Example of CAMP User Interface

The camp command will use the default camp hostname (bnmrvw in Figure 1). The camp hostname is contained in the environment variable CAMP_HOST, defined at login (in ~/.cshrc). The camp hostname is also defined in the ODB at path /Equipment/FIFO_acq/mdarc/camp/camp hostname for the use of the DAQ system. The name should be the same as CAMP_HOST.

To access the Camp User Interface using a different camp host, specify the camp hostname, e.g.

[bnmr@isdaq01 ~]camp -node polvw

CAMP in BNMR/BNQR

The CAMP system is used for two purposes in the BNMR/BNQR experiments:

• for logging of CAMP data to the saved file
• for the CAMP scan experiment(s) (1c) and

   Logging of CAMP data to the saved file is handled differently for
   Type 1  (I-MUSR) runs  or
   Type 2 (TD-MUSR)  runs.
