Inconel alloy 718 is a high-strength and corrosion resistant alloy that is commonly used as a beamline vacuum window. The accumulation of irradiation-induced damage substantially decreases the window's service lifetime, and replacing it engenders significant beamline downtime. With this application in mind, herein we examine whether post-irradiation annealing can alleviate irradiation-induced damage of Inconel alloy 718. Inconel alloy 718 was received in a solution annealed state. We then irradiated samples using two different modalities (1.5 MeV H+ and 5 MeV Ni2+) at three representative temperatures for beamline windows (room temperature, 100 degrees C, and 200 degrees C), followed by annealing at temperatures viable for in-situ annealing processes (no anneal, 300 degrees C, and 500 degrees C). Using nanoindentation, we determined that irradiation-induced hardening occurs but is largely mitigated by post-irradiation annealing. Overall, our results suggest that in-situ annealing of radiation damage in Inconel alloy 718 vacuum windows appears feasible, which could potentially decrease beam downtime and maintenance costs.

Modulation of structure, morphology and wettability of polytetrafluoroethylene surface by low energy ion beam irradiation ATTA, ali; FAWZY, yasser; Bek, Alpan; Abdel-Hamid, Hassan M.; El-Oker, Mohamed M. (Elsevier BV, 2013-04-01) Polytetrafluoroethylene (PTFE) films were irradiated under vacuum with 3 keV Argon ions (Ar+) and fluences ranging from 0.5 x 10(18) to 2 x 10(18) ions/cm(2). Ion induced PTFE surface modifications of structural, morphological and wettability nature were studied by means of Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy, atomic force microscopy and force spectroscopy, and contact angle measurements. FTIR analysis indicated defluorination of PTFE due to the rupture of C-C and C-...
A systematic study on MOS type radiation sensors Yilmaz, Ercan; Kaleli, Buket; Turan, Raşit (Elsevier BV, 2007-11-01) Radiation sensors based on metal oxide semiconductor (MOS) structure are useful because of their superior sensitivity as well as excellent compatibility with the existing microelectronic technology. In this paper, a systematic study of MOS capacitors built on p- and n-type Si substrates with different SiO2 thicknesses (10 nm, 50 nm, 100 nm and 240 nm) is presented. MOS device response to gamma radiation up to 256 Gray have been studied from the sensor application point of view. Variation of the radiation in...
Precise mapping of the magnetic field in the CMS barrel yoke using cosmic rays Chatrchyan, S.; et. al. (IOP Publishing, 2010-03-01) The CMS detector is designed around a large 4 T superconducting solenoid, enclosed in a 12 000-tonne steel return yoke. A detailed map of the magnetic field is required for the accurate simulation and reconstruction of physics events in the CMS detector, not only in the inner tracking region inside the solenoid but also in the large and complex structure of the steel yoke, which is instrumented with muon chambers. Using a large sample of cosmic muon events collected by CMS in 2008, the field in the steel of...
Use of Al(2)O(3) layer as a dielectric in MOS based radiation sensors fabricated on a Si substrate YILMAZ, ERCAN; Dogan, Ilker; Turan, Raşit (Elsevier BV, 2008-11-01) The use of Al(2)O(3) dielectric in MOS based radiation sensors has been investigated. Their response has been compared with conventional MOS capacitors with a SiO(2) dielectric. The study includes gamma radiation effects with dose up to 4 Gy. The effect of radiation has been determined from the valance band shift in CV curves. The amount of charge induced by the radiation has been calculated and compared with the response of MOS capacitors with SiO(2) with the same and different thicknesses. Fading properti...
Nanohardness measurements of heavy ion irradiated coarse- and nanocrystalline-grained tungsten at room and high temperature El-Atwani, O.; Weaver, J. S.; Esquivel, E.; Efe, Mert; Chancey, M. R.; Wang, Y. Q.; Maloy, S. A.; Mara, N. (Elsevier BV, 2018-10-01) Heavy ion irradiation was performed on coarse and nanocrystalline-grained tungsten (CGW and NGW, respectively) at room temperature (RT) and 1050 K from 0.25 to 4 dpa to simulate radiation damage for fusion energy applications. TEM and nanohardness measurements of irradiated samples were made to quantify the radiation tolerance of these two candidate materials. In this case, TEM is used to quantify the defect morphology at low dpa values and determine the barrier strength coefficients of the different defect...
