A silicon-on-insulator diode array with a sensitive depth of 10 microns has been developed for microdosimetry in proton therapy. The detector was coupled to radiation-hard charge amplifier the probe assembly capable measuring an LET down 1.2 keV//spl mu/m. device successfully tested at two therapy centers. 230 MeV Northeastern Proton Therapy Center, Boston and 250 Medical Research Center Tsukuba, Japan. offers much improved spatial resolution compared proportional gas counter particularly...
The Spallation Neutron Source (SNS) is an accelerator-based neutron source being built at Oak Ridge National Laboratory. warm linac portion, designed by Los Alamos, has been installed and commissioned. comprised of six Drift Tube Linac (DTL) tanks four Coupled Cavity (CCL) modules. For commissioning purposes the accelerating systems have operated less than design 6% duty factor. During lower power operation there RF cavity heating. This decrease in heat load causes operational stability...
The Resonance Control Cooling System (RCCS) was designed by Los Alamos National Laboratory for the warm linac of Spallation Neutron Source. primary design focus directed on water-cooling individual component contributions. sizing RCCS water skid accomplished means a specially created SINDA/FLUINT model tailored to these system requirements. A new developed in Matlab Simulink and incorporates actual operational values control valve interactions. took into consideration dependence RF input...

Increasing the pulse repetition rate (PRR) of SNS Linac to its designed maximum 60 Hz provide 1.4 MW beam on target is in progress. Operation above a second also being considered future. PRR 80 would allow additional pulses be diverted target. This paper discusses impact increasing infrastructure including Radio Frequency (RF) systems and structures, ion source, cryogenics, controls
The Spallation Neutron Source (SNS) linac has a high gradient and 2 MW of beam power, it therefore requires substantial RF power cooling. There are 94 klystrons in its system, large number for proton linac. optimization process logic that lead to the klystron, transmitter, supply sizes is discussed. We also describe requirements building tunnel area, electrical water this system. trade-off decisions between low capital cost, operating good maintainability described.
