Title: On detector calibration and characterization “High Altitude Water Cerenkov (HAWC)” in the phase HAWC100.

Abstract. The High Altitude Water Cherenkov (HAWC) Observatory is a TeV gamma ray detector currently under construction at Sierra Negra in Mexico. HAWC will utilize the wide-angle, high duty cycle water Cherenkov technique developed by Milagro, but use new technology, a larger detection area, and higher altitude to improve sensitivity by an order of magnitude. HAWC will survey the TeV gamma ray sky, measure spectra of galactic sources up to and beyond 100 TeV, and map galactic diffuse gamma ray emission. With its wide field of view and continuous operation, HAWC will also be a powerful instrument with which to study transient phenomena. HAWC will have significant overlap with space and ground-based detectors like NASA-FERMI, MAGIC, HESS, AUGER and ICECUBE. The amount of information will be handled in the order of Peta-bytes, so for processing and storage technologies are used characteristic of high performance computing (parallel processing, multi-threads). The student will contribute through simulations the performance of the instrument and analysis of data obtained by Monte Carlo techniques and simulate the performance of the detector at various stages. Will generate cascades of product particles from collisions of cosmic rays with the atmosphere. These simulations will be compared with data taken with the HAWC30 to start the installation phase HAWC100. Will develop models of noise and will subtracting this method as background noise to the signal recorded by HAWC.
