Measurement of radiation hardness of PET components
2009 IEEE Nuclear Science Symposium Conference Record (NSS/MIC), 2009IN-BEAM PET has given valuable feedback on treatment quality over the 11 years of operation time between 1997 and 2008 of the heavy ion treatment facility at the Gesellschaft fu¨r Schwerionenforschung (GSI) Darmstadt [1]. Based on this technical expertise a next generation of in-beam PET scanners will be developed. An experiment addressing the question

The effect of laser radiation on CdZnTe radiation hardness
Journal of Instrumentation, 2011The possibility to increase the radiation hardness of Cd0.9Zn0.1Te crystal using pulsed Nd:YAG laser radiation was shown. Estimation of the crystalline lattice defects before and after irradiation by γ-ray using photoluminescence method in the experiments was applied.

Increased radiation hardness of CdZnTe by laser radiation
IEEE Nuclear Science Symposuim & Medical Imaging Conference, 2010The aim of this work is to study the possibility to increase the radiation hardness of Cd 0.9 Zn 0.1 Te crystal using laser radiation. Pulsed Nd:YAG laser for this aim was used. Estimation of the crystalline lattice defects before and after irradiation by γ-ray using photoluminescence method in the experiments was applied.

Radiation damage studies of new intrinsically radiation-hard scintillators
2016 IEEE Nuclear Science Symposium, Medical Imaging Conference and Room-Temperature Semiconductor Detector Workshop (NSS/MIC/RTSD), 2016Following the development of intrinsically radiation-hard scintillators, we exposed various scintillators tiles to gammas from a 137Cs source at the University of Iowa Hospitals and Clinics up to 1.4 and 14 Mrad. The results are within expectations and exhibit sufficiently high performance for implementations in the future/upgrade hadron/lepton ...

Radiation Hardness of Josephson Devices
Japanese Journal of Applied Physics, 1998We have experimentally investigated the effects of intense proton beam irradiation (fluence up to 1016 p/cm2 and dose up to 5 Grad) and ion beam irradiation (fluence up to 1.3×1012 ion/cm2 and dose up to 0.92 Grad) at room temperature on Josephson junctions, junction arrays and RSFQ digital devices.

A radiation hard septum magnet
IEEE Transactions on Magnetics, 1981A septum magnet, used to separate a pion beam from a high intensity proton beam, has been designed, built and tested at TRIUMF. Because the proton beam intensities car exceed 100 μA, and it is anticipated that ∼ 1% of the beam will be spilt on the septum magnet, all components of the magnet have to be radiation hard (i.e., inorganic).

This paper examines currently existing fibers of nearly all types that show sufficient radiation hardness in lengths necessary for their respective applications. It also considers hydrogen loading or treatment and thermal or photo bleaching which can harden certain fibers or fiber links.

Radiation Hardness of Ovonic Devices
IEEE Transactions on Nuclear Science, 1968Ovonic threshold switches have been exposed to pulses of flash X-rays to levels of 1.8×1011 rads/sec and to fast neutron fluences of as high as nvt = 1.2×1017 n/cm2. The switching devices have continued to function during the transient of the X-ray flash and experienced no permanent damage or change of their electrical parameters in excess of the ...

Abstract The ISAC RIB facility at TRIUMF utilizes up to 100 μA from the 500 MeV H − cyclotron to produce RIB using the isotopic separation on line (ISOL) method. In the moment, we are mainly using a hot surface ion source and a laser ion source to produce our RIB.
