Automatic CAMP variables are listed in ODB at path {{Odbpath|path=/Equipment/FIFO_acq/mdarc/camp/}} and can be easily accessed by '''clicking on the alias link "AutoHeaders" ''' in the section "Review Run Parameters" on the Custom Status Page (Figure 1).  This will result in a page displayed similar to Figure 2.

The user enters the required CAMP path for "temperature variable" and "field variable", or blank if not used. The CAMP paths must be written exactly as they appear in the
[[#CAMP User Interface]].  Automatic CAMP variables (if defined) are saved for both Type 1 and Type 2.

The Automatic Headers subtree can be found at ODB path  {{Odbpath|path=/Equipment/FIFO_acq/mdarc/camp}}. It contains the [[#Automatic CAMP variables]] for logging. Also see [[#Automatic CAMP variables|above]] for access to this directory via alias-link, and an example.
The ODB Keys found in this directory are explained below.

</div>
This key in the [[#ODB Keys in the Automatic Headers subtree|Automatic headers subtree]] contains the name of the MVME host running CAMP. See examples at [[#CAMP Hostname]]. If the CAMP hostname is NOT blank, the CAMP host must be booted up and available for use.
The CAMP host is "pinged" before attempting access, to try to avoid a complete hangup of [[mdarc]] if the CAMP host is powered down. If the CAMP host is not responding or logging is turned off, the run start may fail, or a warning message will be displayed each time a file is saved.

Introduction

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

CAMP Hostname

The CAMP Hostname is

  • bnmrvw.triumf.ca for the bnmr experiment or
  • polvw.triumf.ca for bnqr experiment

The CAMP hostname is set in two places in the DAQ system :

  1. The environment variable CAMP_HOST
  2. In the ODB at Scanning/Camp/Settings/Server name

CAMP in BNMR/BNQR

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

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 defined by the environment variable CAMP_HOST (bnmrvw.triumf.ca in Figure 1). To access the Camp User Interface using a different camp host (temporarily), specify the camp hostname, e.g. 

[bnmr@isdaq01 ~]camp -node polvw
