Installation and Test of a Scintillator-Based, Ultra-High Vacuum Compatible Particle Detector at CRYRING for the Beam Time Period 2023-2024ONLINE ONLY

CRYRING@ESR facility from FAIR requires the usage of dedicated beam diagnostics systems compatible with ultra-high vacuum (UHV) conditions (up to 10-12 mbar), mechanical strength, high temperature resistance  and good tolerance for radiation. [1,2]
An elegant, yet simple approach consists of using scintillator crystals (YAP:Ce) installed inside  UHV that are coupled through a quartz window to an external photomultiplier. [3,4].

This presentation will systematically describe the installation of such a detector. During the activity carried out at GSI in the two months, I actively participated in the installation of a scintillator detector after the experimental section YR09 from Cryring@ESR. Since this detector was already installed in another area of interest, it was necessary to move the entire assembly, which includes the frame and the manipulator of the detector head, to the new assigned area. The presentation will have a technical orientation including:

-A short introduction in which the reason for installing this detector is argued

-Installation of the manipulator assembly in the new designated area

-Assembling and mounting the detector head

-Troubleshooting and cold testing of the detector head (241-Am)

-Data analysis and perspectives for improving future performance
