In-beam test results of the Super-FRS GEM-TPC detector prototype with relativistic uranium ion beam

Cherenkov detector of the AMS experiment : test beam results with a prototype

The Alpha Magnetic Spectrometer (AMS) to be installed on the International Space Station (ISS) will be equipped with a proximity Ring Imaging Cherenkov (RICH) detector for measuring the velocity and electric charge of the charged cosmic particles. This detector will contribute to the high level of redundancy required for AMS as well as to the rejection of albedo particles. Charge separation up ...

Beam test of a Time-of-Flight detector prototype

We report on results of a Time-of-Flight, TOF, counter prototype in beam tests at SLAC and Fermilab. Using two identical 64-pixel Photonis Microchannel Plate Photomultipliers, MCP-PMTs, to provide start and stop signals, each having a 1 cm-long quartz Cherenkov radiator, we have achieved a timing resolution of σSingle_detector ~14 ps. To be published in Nucl. Instr.& Methods ——— • Manuscript re...

Ion Beam Heating of Liquid Jet Li Target for the Super-FRS

Survival of the production target over an extended period of time is a very important problem for the SuperFRS. It has been shown [1,2] that a solid graphite target can be used for up to 10 ions per bunch in a fast extraction mode. For higher intensities, one should develop an alternative scheme, for example, a liquid jet metal target. In this contribution we present 3D computer simulations of ...

Beam Test Results of the BTeV Silicon Pixel Detector

The results of the BTeV silicon pixel detector beam test carried out at Fermilab in 1999-2000 are reported. The pixel detector spatial resolution has been studied as a function of track inclination, sensor bias, and readout threshold.
