A cryogenic target for Compton scattering experiments at HIγS

A cryogenic target for Compton scattering experiments at HIγS

We have developed a cryogenic target for use at the High Intensity γ-ray Source (HIγS). The target system is able to liquefy 4He at 4K, hydrogen at 20K, and deuterium at 23K to fill a 0.3L Kapton cell. Liquid temperatures and condenser pressures are recorded throughout each run in order to ensure th...

Zusammenfassung:We have developed a cryogenic target for use at the High Intensity γ-ray Source (HIγS). The target system is able to liquefy 4He at 4K, hydrogen at 20K, and deuterium at 23K to fill a 0.3L Kapton cell. Liquid temperatures and condenser pressures are recorded throughout each run in order to ensure that the target's areal density is known to ∼1%. The target is being utilized in a series of experiments which probe the electromagnetic polarizabilities of the nucleon.
