Radiation Performance Data of the Fast-, Light-cured Plastic Scintillator Formulations

This repository contains the waveforms from the CAEN DT5730 digitizer of the fast-, light-cured plastic scintillators for the different formulations used in the two level-factorial parameter study (AFIT101-130) and ethanol treatment study (AFIT220-230). Each scintillator was wrapped with two layers of MIL-T-27730A PTFE tape and coupled to a 2" Hamamatsu R7724 PMT biased at -1050 V. The signals were recorded using CAEN CoMPASS software on a CAEN DT5730 digitizer while the scintillators were exposed to Na-22, Cs-137, and AmBe radiation sources. Some of the scintillator formulations were measured more than once, but due to the limitations of the data that can be saved in this repository, not all the experimental data is included; however, this repository consists of the data closest to the average performance of each scintillator. Additionally, the EJ-276 dataset is included. The table below lists the weight percentage of the compounds in each scintillator formulations. The compounds for each formulation were weighed and placed into a 20 mL reaction vial. The compounds were thoroughly mixed together using an alternating combination of an ultrasonic bath and hot plate to gently warm the mixture. To reduce oxygen-induced quenching, the reaction vial was transferred to a glove box pressurized with a nitrogen atmosphere and dissolved oxygen was removed by sparging with nitrogen for 10 min. The reaction vial was sealed before removal from the glove box. Next, the resin solution was cured using a commercially-available 405 nm Formlabs Form Cure for 5 mins and Dymax BlueWave AX-550 VisiCure for 4 mins. Finally, all solid scintillators were sanded and polished using 180 grit, 400 grit, 1000 grit, and 2000 grit sandpaper and a 300~nm alumina slurry.
