Target/Beam Monitoring & Instrumentation
Contributed Focus Session Oral Presentation
We have developed a Multi Wire Profile Monitor system by using SiC wires to built reliable and long life profile monitor system at the JSNS in J-PARC.
In order to obtain two dimensional beam profile at the target of the spallation neutron source, it was developed that beam monitoring technique based on the activation technique by using imaging plate with remote handling devices. It is shown...

Contributed Focus Session Oral Presentation
A new system, called the Beam Position Thermometer, was built to monitor the position of the proton beam just before the NuMI target. It tracks beam poisiton by measuring beam heating of a grid of wires, read out by thermocouples. It has been in operation since September 2013. The criteria were that the monitor had to have better than half-millimeter accuracy, it had to be robust and stable...

Target/Beam Monitoring & Instrumentation
Contributed Focus Session Oral Presentation
We present the concept for a radiation detector based on measuring the reaction products from a multiple-component fluid exposed to radiation. This detector will be useful for long-term measurements in high-radiation areas where other detector technologies may not survive. The approach uses a gas or compressible liquid composed of reactants that are predominantly stable in standard...

CERN is developing a Pb-Bi target as a test for on-line production of radioactive beams at ISOLDE, to anticipate the increase of beam power that will be available after the connection of the new LINAC4 to the CERN injector complex. Beam power of up to 10 kW will become available, with power densities deposed in the target material comparable to facilities in the hundreds of kW regime.
The...

VIMOS is a dedicated safety system developed at the Spallation Neutron Source SINQ at the Paul Scherrer Institut, PSI, in Switzerland. VIMOS very directly monitors the correct current density distribution of the proton beam on the target by sampling the light emitted from a glowing mesh heated by the passing protons. The design has been optimized for obtaining maximum sensitivity and timely...

Target/Beam Monitoring & Instrumentation
Contributed Focus Session Oral Presentation
The Target Imaging System (TIS) shows the size and position of the proton beam on the SNS Target which is coated with Cr:Al2O3 layer that luminesces where the proton beam hits. The light from this coating is transferred through mirrors and optical fibers to a digital camera outside the high radiation area. The TIS is used during operations to verify that the beam is in the right location and...
