Proposal to observe half-bare electrons on a 45-MeV linac

Interacting electrons on a half line coupled to impurities

We generalize the bosonization methods for systems in the half line that we discussed elsewhere, to study the effects of interactions on electronic systems coupled to impurities. We introduce a model for a quantum wire coupled with a quantum dot by a purely capacitive interaction. We show that the effect on the quantum wire is a dynamical boundary condition which reflects the charge fluctuation...

POHANG NEUTRON FACILITY BASED ON 100-MeV ELECTRON LINAC

Pohang Neutron Facility (PNF) is a pulsed neutron facility based on the 100-MeV electron linear accelerator. It was constructed for nuclear data production in Korea, and it consists of an electron linear accelerator, a watercooled Ta target with a water moderator and a time-offlight path with an 11 m length. The 100-MeV electron linac uses a thermionic RF-gun, an alpha magnet, four quadrupole m...

High Gradient Linac Prototype : A Modest Proposal *

A New 180 MeV H Linac for Upgrades of ISIS

Several options have been studied to raise the beam power of the ISIS spallation neutron source to a level of 1 MW with the possibility of going to 4-5 MW in the longer term [1]. All scenarios can operate in 2 modes, where the beam power is either delivered to a spallation target or, alternatively, to a target suitable to produce muons via pion decay for a neutrino factory. A more recent upgrad...

Demonstration of Plasma Beat Wave Acceleration of Electrons from 2 MeV to 20 MeV

We describe the results from recent experiments1 on the plasma beat wave accelerator (PBWA) scheme at UCLA. A relativistic electron plasma wave (which is the accelerating structure) is resonantly excited in a plasma by the beating of two co-propagating electromagnetic waves (obtained from a CO2 laser operating simultaneously on two wavelengths). A 2 MeV, 200 mA (peak-current) electron beam, rou...
