Srf
Adult skeletal muscles adapt their fiber size to workload. We show that serum response factor (Srf) is required for satellite cell-mediated hypertrophic muscle growth. Deletion of Srf from myofibers, and not satellite cells, blunts overload-induced hypertrophy, and impairs satellite cell proliferation and recruitment to pre-existing fibers. We reveal a gene network in which Srf within myofibers...
متن کاملSRF for Muon Colliders
Interest in the Muon Colliders is growing [1]. Electronpositron colliders beyond 2 TeV CM energy are likely to limited by background from beamstrahlung, and proton colliders beyond 20 TeV CM are likely to be limited by the sheer size of the multi-hundred km circumference. Being 200 times more massive than electrons, muons do not suffer from beamstrahlung limits. A 3 TeV muon collider is likely ...
متن کاملWisconsin Srf Electron Gun Commissioning*
The University of Wisconsin-Madison has completed installation of a superconducting electron gun. Its concept was optimized to be the source for a CW free electron laser facility with multiple megahertz repetition rate end stations. This VHF superconducting configuration holds the promise of the highest performance for CW injectors. Initial commissioning efforts show that the cavity can achieve...
متن کاملMultiscale mechanisms of SRF breakdown
Multiscale mechanisms of SRF breakdown and the dependence of the quality factor Q(H0) on the rf field amplitude H0 are discussed. We first consider a basic nonlinear dependence of the surface resistance Rs on the rf screening current density J, which becomes crucial at rf fields of the order of the thermodynamic critical field H c 200 mT. The current-induced rf pairbreaking in the clean limit r...
متن کاملHigh-current Srf Cavity Design
For high current applications, it is desirable for the cavity shape to have a low longitudinal loss factor and to have a high beam-breakup threshold current. This paper briefly describes three different cavities designed for this purpose: a six-cell elliptical cavity for particles traveling at the speed of light, a two-cell elliptical cavity for subluminal particle speeds, and a single cell cav...
