A charged-particle beam passing through a dielectric sheet releases carriers whose collection serves to detect the beam. A simple device to demonstrate this effect has been constructed and tested. By applying sufficient bias to electrodes on the faces of the dielectric sheet, the device can be operated at gains of 1000 or more. The device shows promise of applicability to positionsensitive and single-particle detection.

    Two types of switched electrode electronics beam position monitors are in use at Jefferson Lab. Together they provide accurate beam position to the control system for beam intensities between 50 nA and 2 mA. One version, called the linac style, has a switching frequency of 125 kHz. The other,...

    Plans to eliminate the positron accumulator ring (PAR) from the Advanced Photon Source (APS) injector complex have created the need for a device to limit the allowable beam charge injected into the APS injector synchrotron. The beam shut-off current monitor (BESOCM) was chosen to provide this...

    Over the whole circumference of the LHC, Beam Loss Monitors (BLM) will be needed for a continuous surveillance of fast and slow beam losses. In this paper, the location of the BLMs set outside the magnet cryostats in the arcs is proposed. In order to know the number of protons lost on the beam...
