The Front End Enclosure (FEE) of the Linac Coherent Light Source (LCLS) is a shielding housing located between the electron dump area and the first experimental hutch. The upstream part of the FEE hosts the commissioning diagnostics for the FEL beam. In the downstream part of the FEE, two sets of grazing incidence mirror and several collimators are used to direct the beam to one of the experime...

The GEANT/FLUKA detector simulation and particle interaction package was used to develop a Monte Carlo program to estimate atmospheric secondary ux produced by primary cosmic rays, as a function of depth in the atmosphere. Of special interest is the calculation of secondary electrons and positrons near the top of the atmosphere. The HEAT instrument measured primary and secondary electrons rangi...

The Linac Coherent Light Source (LCLS), the world’s first hard xray free electron laser is under construction at the Stanford Linear Accelerator Center and is expected to be completed in 2009. LCLS will deliver unprecedented bright and short x-ray laser pulses that shall enable frontier new science research in biology, nanomaterials and non-crystalline imaging. Over 400 m of LCLS tunnel have be...

Monte Carlo simulations have been carried out using the FLUKA code to improve the neutron ambient dose equivalent [H*(10)] response of the ZReC (zirconium-lined portable neutron counter responding satisfactorily to neutrons up to 1 GeV) by introducing various neutron absorbers in the system such as cadmium, gadolinium, natural boron, enriched (10)B and borated polythene. It was found that ZReC ...

A new method to estimate remanent dose rates, to be used with the Monte Carlo code FLUKA, was benchmarked against measurements from an experiment that was performed at the CERN-EU high-energy reference field facility. An extensive collection of samples of different materials were placed downstream of, and laterally to, a copper target, intercepting a positively charged mixed hadron beam with a ...

For the production of a clinical 15 MV photon beam, the design of accelerator head assembly has been optimized using Monte Carlo based FLUKA code. The accelerator head assembly consists of etarget, flattening filter, primary collimator and an adjustable rectangular secondary collimator. Accelerators used for medical radiation therapy generate continuous energy gamma rays called bremsstrahlung r...

An extensive 3-dimensional Monte Carlo calculation of the atmospheric neutrino flux is in progress with the FLUKA Monte Carlo code. The results are compared to those obtained under the 1-dimensional approximation, where secondary particles and decay products are assumed to be collinear to the primary cosmic ray, as usually done in most of the already existing flux calculations. It is shown that...

Within the scope of the R3B experiment at FAIR, a highly efficient time-of-flight spectrometer for high-energy neutrons (200 to 1000 MeV) is developed, called NeuLAND (new Large Area Neutron Detector). The design goals and an overview of the project is given in the contribution of T. Aumann et al. [1]. Here we present the detector concept based on a fully active detector built with only organic...
