THPOSRP06	A Test Bench for Characterizing Electron Cooler Components at up to -80 kVDC	61
	G. Khatri, J. Cenede, A. Frassier, G. Tranquille CERN, Meyrin, Switzerland
	During the upcoming Long Shutdown 3 (LS3), the electron cooler of CERN’s Antiproton Decelerator (AD) will be replaced by a new electron cooler. The present electron cooler operates at the maximum energy of about 27keV. However, the new device will have electron collector and electron gun with the possibility of operating at up to 68keV electron energy. To characterize the gun and the collector at this higher energy, a test bench has been built and put in operation. The test bench is equipped with a 1.5 m drift solenoid operating with a maximum magnetic field of 1000 Gauss, and a faraday cage with a high voltage platform that can be biased up to - 80 kV DC. The first element of the new AD electron cooler, the electron collector, is presently being tested on the test bench. In this poster we describe in detail the main elements of the test stand, give some highlights of the ongoing tests with the new collector and present future plans.
