Functions of the Beam Intensity Redundant
Electronic Unit
Throughout the PTS a number of electrometers are installed. Electrometers are
connected to Beam Profile Monitors (BPMs) and Beam Current Monitors (BCMs).
An electrometer reads out very small currents and performs some basic calculation
on the acquired data that it transmits to the Beam Operation Manager (BOM).
One of the electrometers is called the Beam Intensity Redundant Electronic Unit
(BIREU), which is connected to the ionization chamber of the cyclotron (IC cyclo).
Note: If the BIREU is not (yet) installed at your center, the cyclo IC chamber is
connected to the Beam Current Comparator Electronic Unit (BCCEU).
The BIREU performs the following functions:
 Perform a Max Current Check
 Provide a Dosimetry Counter Electronic Unit (DCEU) output to enable
measurement of the overall dose delivered by the cyclotron
BIREU Startup or Connection Failure
In case the BIREU cannot start or fails to connect, the following error message
appears:
