We present results of the commissioning of a new injector for the Brazilian Synchrotron Light Source. The new injector consists of the existing 125-MeV LINAC and a new 500-MeV booster synchrotron. At present, about 40 mA can be injected into the booster and about 15 mA can be ramped up to 500 MeV at a repetition rate of 0.17 Hz. The new injector has allowed the accumulation of up to 540 mA in t...

Construction of a compact 2.4 Tm Cooler Injector synchrotron (CIS) to injection intense polarised proton and deuteron beams into the IUCF 3.6 Tm electron cooled storage ring (Cooler) is complete. Beam commissioning began in 1997 with unpolarized H strip injection and progressed to the extraction of 210 MeV protons from CIS and the injection of 10 protons at 200 MeV into the Cooler for experimen...

A prototype of the MeV gamma-ray imaging camera based on the full reconstruction of the Compton process has been developed. This camera consists of a micro-TPC that is a gaseous Time Projection Chamber (TPC) and scintillation cameras. With the information of the recoil electrons and the scattered gamma-rays, this camera detects the energy and incident direction of each incident gamma-ray. We de...

The FOOT (FragmentatiOn Of Target) experiment aims to measure the fragmentation cross-section of protons into H, C, O targets at beam energies interest for hadrontherapy (50-250 MeV H and 50-400 MeV/u C ions). Given short range fragments, an inverse kinematic approach requiring precise tracking capabilities in a magnetic volume has been chosen. A key subsystem this will be Microstrip Silicon De...

Chemical and thermal freeze–out of the hadronic fireball formed in symmetric collisions of light, intermediate–mass, and heavy nuclei at beam energies between 0.8A GeV and 2.0A GeV are discussed in terms of an equilibrated, isospin–symmetric ideal hadron gas with grand–canonical baryon–number conservation. For each collision system the baryochemical potential µ B and the chemical freeze–out tem...

Novel lead oxide-based flexible dosimeters with superior performance were experimentally tested for electron therapy. However, absorbed/transmitted primary particle fraction and secondary radiation distribution from the dosimeter surface have not been reported. These features should be specified to improve dosimeter’s reliability medical applications. Hence, absorbed fraction, transmitted radia...

The Laboratório do Acelerador Linear (LAL) of the Physics Institute of the University of São Paulo (IFUSP) is building a 31 MeV continuous wave (cw) racetrack microtron [1][2]. This two-stage microtron comprises a 1.8 MeV injector linac, a five-turn microtron booster that increases the energy to 4.9 MeV, and the main microtron, which delivers a 31 MeV cw electron beam after 28 turns. The inject...

Multiple Coulomb Scattering (MCS) is a well known phenomenon occurring when charged particles traverse materials. Measurements of muons traversing low $Z$ materials made in the MuScat experiment showed that theoretical models and simulation codes, such as GEANT4 (v7.0), over-estimated scattering. The Muon Ionization Cooling Experiment (MICE) measured cooling muon beam liquid hydrogen or lithium...
