Timber

Timber variables

LHC -> Beam Instrumentation -> Beam Profile -> BGV Demonstrator

The prefix BGVDA.A7L4.B2 should be used for all BGV Demo variables.

This prefix follows the standard Timber variable naming conventions used in the LHC. It can be interpreted as follows:

• BGVDA is a name used for the mechanical drawings related to the BGV D*etector, model *A
• A7L4 is a bit more tricky. It could be interpreted as a vacuum sector, but this is not correct: the BGV Demonstrator is located in vacuum sector B7L4. Names like X7L4 are used in the LHC layout database to name subsystems / devices. The letter X is replaced by a letter A, B, C, ... depending on the location of the device with respect to the IP
• Therefore, BGVDA.A7L4.B2 should be interpreted as follows: BGV detector system, subsystem located closest to the IP
• Although this prefix is not so useful for the people familiar with the BGV, it is a meaningful reference to the system and its location

The temperature readings are of type integer. The Timber logging is made whenever there is a change >= 1 °C. In addition, the values are logged every hour (even if there is no change).
