Description
The 3rd CLIC Test Facility, built by an international collaboration at CERN, addresses feasibility issues of the CLIC RF source and the two-beam acceleration scheme. In particular, the Test Beam Line (TBL), is a small-scale drive beam decelerator and studies the transport of a high current electron beam as it is being decelerated in several Power Extraction and Transfer Structures (PETS). With a maximum of 16 structures, the beam will be decelerated from 150 to a minimum of 69 MeV, while its energy spread increases significantly. In order to monitor the energy loss a segmented beam dump for fast time-resolved spectrometry has been designed and installed at the end of the TBL. The segmented dump provides single-shot spectra with a 1.2% resolution on energy and a 5 ns temporal resolution. Complementary to this, a single-slit dump, which provides fast spectrometry based on a multi-shot dipole scan technique, is installed at the beginning of the line, thus providing a measurement for comparison. This paper presents the first beam measurements at TBL, with an estimation of the performance of the segmented beam dump.
