A Pulsed Drift Tube for 100keV Antiprotons — •Jonas Fischer, Alexandre Obertelli, and Frank Wienholtz — IKP TU Darmstadt, Deutschland
The PUMA collaboration aims at trapping, storing and transporting 109 antiprotons in a cryogenic penning trap. To achieve this, antiprotons from ELENA need to be decelerated from 100keV to 4keV in a first step. To minimise losses in the deceleration process, a Pulsed Drift Tube (PDT) was installed at LNE51 at CERN. A good vacuum of below 10−10 mbar is necessary to avoid the annihilation of the antiprotons with residual gas molecules. This, and the high voltage, pose strict restrains on the design and operation of the pulsed drift tube. In this talk I will give an overview over the pulsed drift tube designed for PUMA.
