“…The BFEM differed from BTEM in that 6 silicon tracker layers were removed and the data acquisition system was reconfigured. The BTEM was tested with e − , e + and gamma beams at the Stanford Linear Accelerator Center (SLAC), and the results were published (Couto e Silva et al (2001)). The BFEM ACD consisted of 13 segmented plastic anticoincidence scintillators to help identify the background events due to charged particles.…”

Cosmic-ray background fluxes were modeled based on existing measurements and theories and are presented here. The model, originally developed for the Gamma-ray Large Area Space Telescope (GLAST) Balloon Experiment, covers the entire solid angle (4π sr), the sensitive energy range of the instrument (∼ 10 MeV to 100 GeV) and abundant components (proton, alpha, e − , e + , µ − , µ + and gamma). It is expressed in analytic functions in which modulations due to the solar activity and the Earth geomagnetism are parameterized. Although 1 present address: Computer Software Development Co., Ltd., 2-16-5 Konan, Minato-ku, Tokyo 108-0075, Japan -2 -the model is intended to be used primarily for the GLAST Balloon Experiment, model functions in low-Earth orbit are also presented and can be used for other high energy astrophysical missions. The model has been validated via comparison with the data of the GLAST Balloon Experiment.

“…The UCSC-LLUMC tracker [23] uses silicon microstrip detectors readout by ASICs both originally developed for the Gamma-Ray Large Area Space Telescope (GLAST) [24]. The single-sided, AC coupled p-on-n sensors are manufactured from high resistivity wafers of 400 µm thickness, with a strip pitch of 194 µm and outer dimensions of 6.4x6.4cm 2 .…”

“…The tracker measures hit positions with an error of about 50 µm and could also be used to estimate the energy of the crossing particles in the 20-300 MeV range. This is done measuring the specific energy loss in each silicon sensors using the time over threshold (TOT) [24][25] and then extrapolating the original particle energy. A new tracker made by four measuring planes assembled with 236 µm pitch sensors, has been realized by the same collaboration and integrated with a CsI calorimeter [12].…”

In hadron therapy a highly conformed irradiation field is delivered to the target by precisely moving the particle beam and, at the same time, modulating its energy with the aim to cover the tumor volume with the requested dose sparing the surrounding healthy tissues as much as possible. To setup a robust treatment plan the Stopping Power (SP) map for each patient should be measured and the volume to be irradiated precisely located.To improve the precision of the SP map determination the use of a proton beam to perform a 'proton Computed Tomography' (pCT) could be the ideal solution. To be effective in reducing the uncertainties in dose spatial distribution, this novel method should keep the SP map spatial resolution below one millimeter.Tracking in presence of large multiple scattering will be discussed in these proceedings together with the concept of 'most likely path' (MLP). A generalization of the studies on this issue will be introduced with the aim to describe instrumental effects on the MLP spatial resolution.The pCT apparatus, based on a Silicon microstrip tracker followed by a calorimeter to measure single protons trajectory and their residual energy, will be reviewed with particular emphasis on the R&D ongoing on this subject and the results already obtained. New prototypes presently under construction, which will be suitable for pre-clinical studies, will be described too.

“…The SSDs provide information about the position of the particle track from the strip-hit information, and about the particle's energy via the energy deposition measured in each detector. This system, described in greater detail in [22], [24], permits measurements of the lateral proton position to about 50 m and determination of the energy of protons in the 20-300 MeV range. The proton energy is derived from the specific energy deposition in each SSD using the time over threshold (TOT) signal as described in [24], [25].…”
