2 Introduction One crucial issue for applications of scintillation crystals in HEP calorimeters is radiation damage in severe radiation environment, such as at the HL-LHC, with cm -2 s -1 luminosity and 3,000 fb -1 integrated luminosity, up to 130 Mrad ionization dose, charged hadrons/cm 2 and n/cm 2 will be expected. In this paper, we report an investigation on neutron induced radiation damage in BaF 2, LYSO and PWO crystals by using the neutrons at the Weapons Neutron Research facility of Los Alamos Neutron Science Center (WNR facility of LANSCE). In 2015 (Exp. 6991), 18 LFS plates of mm3 were irradiated. In 2016 (Exp. 7332) 36 samples of 5 mm thick LYSO, BaF 2, and PWO were irradiated. 10/25/17 NSS17, N22-6, by Liyuan Zhang, Caltech. 2
3 Neutron Irradiation at LANSCE Los Alamos Neutron Science Center (LANSCE) Samples are placed at Target-4 East Port, about 1.2 m away from the neutron production target. East Port Target-4 10/25/17 NSS17, N22-6, by Liyuan Zhang, Caltech. 3
4 n/ɣ/p Spectra and Production Rate Neutrons/Photons/Protons fluxes are calculated by using MCNPX (Monte Carlo N-Particle extended) package. Plotted spectra are tallied in the largest sample volume (averaging) 10/25/17 NSS17, N22-6, by Liyuan Zhang, Caltech. 4
5 Radiation Dose and Fluence Calculation In 2015 run, 18 LFS plates of mm3 were divided into three groups of six each, and were irradiated for 13.4, 54.5 and 118 days respectively. The fluence of each kind of particle was calculated by integration of 800 MeV proton beam current and MC production rate. 10/25/17 NSS17, N22-6, by Liyuan Zhang, Caltech. 5
6 Fluence and Dose in Exp (2015) According our proton irradiation test result, the effect of the proton fluence and dose is negligible. The photon ionization dose of up to 230 Mrad is significant, comparing to neutron fluence. Particles Group 1 Fluence (cm -2 ) Group 2 Fluence (cm -2 ) Group 3 Fluence (cm -2 ) Thermal and Epithermal (0<En < 1 ev) 7.01E E E+15 Slow and Intermediate Neutrons (1 ev <En < 1 MeV) 2.56E E E+16 Fast neutrons 1 (En > 1 MeV) 2.24E E E+15 Fast neutrons 2 (En > 20 MeV) 4.34E E E+14 Protons (Ep>1 MeV) 5.31E E E+12 Protons Dose (rad) 1.39E E E+05 Photons (Eg>150 KeV) 6.71E E E+15 Photons Dose (rad) in Air 2.40E E E+08 10/25/17 NSS17, N22-6, by Liyuan Zhang, Caltech. 6
7 Light Output Loss of LFS Plates The light response of LFS samples, group-1, 2 and 3, was measured before and after the neutron irradiation. A degradation of 3%,13% and 24% is observed for Group-1, 2 and 3. 10/25/17 NSS17, N22-6, by Liyuan Zhang, Caltech. 7
8 Comparison with γ/p irradiated Samples Neutron irradiated LFS show consistent light output loss vs. EWLT loss, indicating LO loss can be corrected by a light monitoring. Consistent LO loss as a function of ionization dose indicates a negligible neutron induced damage. 10/25/17 NSS17, N22-6, by Liyuan Zhang, Caltech. 8
9 Pb Shielding Introduced in Exp (2016) 5 mm thick Pb shielding was introduced for half of the samples in each group, which attenuated the ionization dose, but not fast neutrons Pb Shielding Capsule (5 mm thick) 10/25/17 NSS17, N22-6, by Liyuan Zhang, Caltech. 9

12 Transmittance of LYSO, BaF 2 and PWO LYSO and BaF 2 show less neutron induced absorption than PWO. Pb shielding reduce RIAC for all 3 kinds of crystals. 10/25/17 NSS17, N22-6, by Liyuan Zhang, Caltech. 12
13 Light Output of LYSO, BaF 2 and PWO LYSO and BaF 2 show less light output loss than PWO. Pb shielding reduce light output loss of LYSO and BaF 2 crystals. 10/25/17 NSS17, N22-6, by Liyuan Zhang, Caltech. 13
14 Summary: LYSO, BaF 2 and PWO LO loss <25% of BaF 2 and LYSO after 200 Mrad plus /cm 2 fast neutrons (>1MeV) indicates an excellent radiation hardness Group No. Crystal With Pb Shielding Without Pb Shielding EWLT Loss (%) L.O.

15 LO Loss vs EWLT Loss Good correlation between LO loss & EWLT loss is observed in all samples, indicating that crystal s LO can be corrected by a light monitoring system LYSO BaF 2 PWO 10/25/17 NSS17, N22-6, by Liyuan Zhang, Caltech. 15
16 RIAC of LYSO, BaF 2 and PWO RIAC consistent with the ionization dose, indicating neutron induced damage is negligible LYSO and BaF 2 show RIAC of 15 and 50 m -1 after 200 Mrad, much less than that of PWO 10/25/17 NSS17, N22-6, by Liyuan Zhang, Caltech. 16
17 LO of LYSO, BaF 2 and PWO LO consistent correlation with the ionization dose, indicating neutron induce damage is negligible 25% LO loss of LYSO and BaF 2 after 207 Mrad plus n/cm -2, indicating their excellent radiation hardness against ionization dose and fast neutrons. 10/25/17 NSS17, N22-6, by Liyuan Zhang, Caltech. 17
18 Summary BaF 2, LYSO and PWO crystals were irradiated by a combination of ɣ-rays, neutrons and protons at LANSCE in 2015 and Less than 25% light output loss is observed in BaF 2 and LYSO crystals after 200 Mrad and n/cm 2, indicating they survive the severe radiation environment expected as the HL-LHC. Radiation damage observed in transmittance and light output is consistent with the ionization dose, indicating neutron induced damage is negligible. This result is consistent with an early observation for PWO crystals irradiated by neutrons up to n/cm 2 at the Saclay reactor. 10/25/17 NSS17, N22-6, by Liyuan Zhang, Caltech. 18
