Beam Loss Detection

Invited Oral

Beam loss monitoring (BLM) is a key protection system for machines using beams with damage potential and is an essential beam diagnostic tool for any machine. All BLM systems are based on the observation of secondary particle showers originating from escaping beam particles. With ever higher beam energies and intensities, the loss of even a tiny fraction of the beam can lead to damage or, in...

Beam Loss Detection

Contributed Oral

In the J-PARC RCS, transverse beam profiles including both the beam core and halo at the extraction beam transport line (3NBT) were measured by using a combination with a wire scanner type beam scraper and beam loss monitors (BLMs). Our final goal of this halo monitor is to measure the intra-bunch beam halo of extracted two bunches from the RCS. Thus the plastic scintillator and...

5. Position Resolution of Optical Fibre-Based Beam Loss Monitors Using Long Electron Pulses

Contributed Oral

Beam loss monitoring systems based on optical fibres (oBLM), have been under consideration for future colliders for several years. To distinguish losses between consecutive quadrupoles, a position resolution of less than 1 m is required. A resolution of better than 0.5 m has been achieved in machines with single, nanosecond long pulses. For longer beam pulses, such as the ~150 ns CLIC pulse,...
