Measurements of Photon Beam Flattening Filter Using an Anisotropic Analytical Algorithm and Electron Beam Employing Electron Monte Carlo

  Introduction: This study aimed to report the measurement of photon and electron beams to configure the Analytical Anisotropic Algorithm and Electron Monte Carlo used in clinical treatment. Material and Methods: All measurements were performed in a large water phantom using a 3-dimensional scanning system (PTW, Germany). ...

Pulsed Electron-Beam Heating

A pulsed, 20 kv electron beam is focussed upon a vapor-deposited thermocouple, and the resulting temperature vs. time response is studied. The experimental data show much scatter, but are consistent with the theoretical prediction that the characteristic thermal response time T is proportional to d , where d is the beam diameter at the thermocouple. From these data, for the soft-glass substrate...

A Pulsed Electron Source for the HITRAP Cooler Trap

The HITRAP Cooler Trap will store highly charged ions and cool them to a temperature of 4 K for delivery to precision experiments [1]. The trap is preceded by a decelerator complex able to slow ion bunches delivered by the ESR from a specific kinetic energy of 4 MeV/u down to 6 keV/u [2]. The Cooler Trap is designed as a 23-ring cylindrical Penning trap, providing the ability to simultaneously ...

Experimental demonstration of relativistic electron cooling.

We report on an experimental demonstration of electron cooling of high-energy antiprotons circulating in a storage ring. In our experiments, electron cooling, a well-established method at low energies (<500 MeV/nucleon), was carried out in a new region of beam parameters, requiring a multi-MeV dc electron beam and an unusual beam transport line. In this Letter, we present the results of the lon...
