In 2004, the US DOE established LHC Accelerator Research Program (LARP) with goal of developing a technology base for future upgrades LHC. The focus magnet program, which is collaboration three laboratories, BNL, FNAL and LBNL, on development high gradient quadrupoles using <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$ Nb_3 Sn$</tex> superconductor. Other program components address issues regarding design, radiation-hard materials, long...
Fermilab is developing and investigating different high-field magnets (HFM) for present future accelerators. The HFM R&D program focused on the 10-12 T based Nb/sub 3/Sn superconductor explored both basic magnet technologies brittle superconductors-wind-and-react react-and-wind. Magnet design studies in support of LHC upgrades VLHC were conducted. A series 1-m long cos-theta dipole models wind-and-react technique was fabricated tested. Three flat racetracks common coil model, a single-layer...

A Time-of-Flight detector (TOF), with a technique based on plastic scintillators and finemesh photomultipliers, has been added to the CDF-II experiment. The main physics motivation is improve neutral B meson flavor determination by K ± identification. expected time resolution 100 ps, which provides at least two standard deviations separation between π for momenta p < 1.6 Gev/cand better than 1.2 over all when combining TOF identification dE/dx using new drift chamber.
Thermoacoustic Oscillations (TAOs) is a commonly experienced phenomenon in helium cryogenics and most cases, an undesirable effect. During LCLS-II prototype Cryomodule (pCM) testing, TAOs were observed both the Cryogenics Distribution System JT Cooldown Valves. The manifested themselves through usual effect of added heat load to cryogenic system ice formation on oscillating device. However, during cavity also found significantly contribute microphonics detuning SRF cavities. Systematic...
Quality factor is a primary cost driver for high energy, continuous wave (CW) SRF linacs like the LCLS-II X-ray free electron laser currently under construction. Taking this into account, several innovations were introduced in cryomodule design to push substantially beyond previous state-of-the-art quality achieved operation. This includes first ever implementation of nitrogen doping cavity treatment, capability provide mass flow cooldown improve expulsion magnetic flux based on recent...

A new test stand dedicated to Superconducting Radiofrequency (SRF) cryomodule testing, CMTS1, has been commissioned and is now in operation at Fermilab. The first device be cooled down powered this facility the prototype 1.3 GHz assembled Fermilab for LCLS-II. We describe demonstrated capabilities of report on steps taken during commissioning, provide an overview results, survey future plans.
Fermilab's 1.3 GHz prototype cryomodule for the Linac Coherent Light Source Upgrade (LCLS-II) has been tested at Cryomodule Test Facility (CMTF). Aspects of design have studied and tested. The cooldown circuit was used to quickly cool cavities through transition temperature, a heater on heat incoming helium warmup. Due 0.5% slope cryomodule, liquid level is not constant along length cryomodule. This as well pressure profile caused management be challenge. microphonics levels in were efforts...
