400-MeV upgrade for the Fermilab linac
Fermilab plans to upgrade the Tevatron to expand the physics research program in both the fixed target and the collider operating modes. The first phase of this program is to increase the energy of the H{sup -} linac from 200 to 400 MeV in order to reduce the incoherent space change tuneshift at injection into the Booster which can limit either the brightness or the total intensity of the beam. The linac upgrade will be achieved by replacing the last four 201 MeV, with seven 805 MHz side-coupled cavity modules operating at an average axial field of about 8 MV/m. This will allow acceleration to 400 MeV in the existing Linac enclosure. 4 refs., 3 figs., 1 tab.

Magnetic Guide Field Measurements and Corrections in the MURA 50‐MeV Electron Accelerator. VI
Methods of measurement and correction of the magnetic fields of the MURA 50‐MeV electron accelerator are described. Measurements of the vertical and horizontal field components were made and the field errors corrected. Correction coils, iron shims, and adjustment of magnet positions were used to produce fields within the required tolerances. Computer methods were used to calculate needed corrections and to evaluate the quality of the corrections achieved.

MURA 50-MeV Electron AcceleratorGeneral Description and Review. I
General descriptions of the history, construction, and operation of the MURA 50‐MeV electron accelerator are given. In its operation, this accelerator has been used to stack large circulating currents of accelerated particles and to investigate multiturn injection, acceleration processes, resonant effects, and collective instabilities.

Integrability and MHV diagrams in N = 4 supersymmetric Yang-Mills theory
We apply MHV diagrams to the derivation of the one-loop dilatation operator of N = 4 super Yang-Mills in the SO(6) sector. We find that in this approach the calculation reduces to the evaluation of a single MHV diagram in dimensional regularisation. This provides the first application of MHV diagrams to an off-shell quantity. We also discuss other applications of the method and future directions. § {a.brandhuber, b.penante, g.travaglini, d.young}@qmul.ac.uk ar X iv :1 41 2. 10 19 v2 [ he pth ] 2 F eb 2 01 5

Free energy and phase transition of the matrix model on a plane wave
It has recently been observed that the weakly coupled plane-wave matrix model has a density of states which grows exponentially at high energy. This implies that the model has a phase transition. The transition appears to be of first order. However, its exact nature is sensitive to interactions. In this paper, we analyze the effect of interactions by computing the relevant parts of the effective potential for the Polyakov loop operator in the finite temperature plane-wave matrix model to three-loop order. We show that the phase transition is indeed of first order. We also compute the correction to the Hagedorn temperature to order two loops.
