Progress continues to be made in setting up GRETINA in the S3 vault. The second hemisphere was installed and both hemispheres’ frames were aligned in front of the S800 spectrograph. The GRETINA data acquisition system now is up and running, and has taken its first data from one GRETINA detector mounted in the frame. The GRETINA filling system was installed and successfully tested and the roof of the S3 vault was closed.
Currently, the marriage between the NSCL data acquisition system with the new S800 readout and GRETINA data acquisition system is underway. Thus far, five GRETINA tracking modules have been received, tested and have been confirmed to be working. Two more modules are on their way from Lawrence Berkeley National Laboratory (LBNL) to NSCL.
A special thanks goes out to all of the visitors who have come to the lab in order to help get GRETINA up and running, including I-Yang Lee, Augusto Macchiavelli, Heather Crawford, Chris Campbell, Mario Cromaz, Carl Lionberger, Tim Loew, and Joe Wallig (LBNL), and Mitch Almond (Oak Ridge National Laboratory).

Site preparation to prepare for FRIB civil construction is on schedule for completion later this month. Relocation of utilities from beneath the footprint of the FRIB buildings is on schedule for substantial completion in June and final completion in December of this year. Civil construction for FRIB will be ready to begin upon DOE approval.
Utility relocation continues, and the new west/east underground steam tunnel has been completed. The Trade Contractors have completed the underground utility tunnel and currently are completing the last portion of steam piping and fittings within the tunnel. When complete, the existing NSCL facility and the buildings to the north will be connected to their permanent steam piping and no further steam work will be required.
Work is nearly complete installing new and relocating existing storm water, water and natural gas piping. Furthermore, the installation of the new electrical 25 MW ductbank that will ultimately serve the FRIB facility has begun and is on schedule for completion this month.
Ten NSCL faculty and staff traveled to Washington DC last weekend for the second USA Science and Engineering Festival. After having phenomenal success at the first such Festival, the lab returned with more helpers and double the booth space to serve the large crowds. Thousands of people came by to try their hand at fragmenting marble “nuclei” and to learn the importance of rare isotope research. Dozens of visitors also inquired about graduate, undergraduate, and outreach programs at NSCL. Many thanks to those who spent their weekend bringing nuclear science to the public: Artemis Spyrou, Irina Sagert, Scott Bustabad, Kortney Cooper, John Novak, Chris Prokop, Jenna Smith, Sophia Vinnikova and Kurt Wiebold.
Work on the Cyclotron-Stopper project has progressed to the point where specialized parts of the device are beginning to be manufactured. The Cyclotron-Stopper is the next generation of gas cell stopping technology, which replaces a linear gas cell with a large circular device that uses the principles of motion in a cyclotron to slow the ions. Work is beginning in the new ReA12 bay to produce the superconducting coils for the project. The machine shop is preparing to cut a wooden test piece before cutting the large steel “hills” on the vertical mill. The iron that makes up the yoke is being prepared in the Bay Cast foundry in Bay City, MI.
The coil winding equipment was moved from the south high bay to the ReA12 bay, including the running of utilities such as compressed air, electricity, internet and phone lines. Besides the coil winding, the ReA12 bay also will be used for receiving the larger parts, staging, assembly and initial testing of the entire magnet.
Much of the winding equipment was used to wind coils for a wide variety of other magnets used throughout the lab. The large turntable was used to wind the A1900 dipole coils, and the clutch table that holds the spool of wire was used for the coils for SUSI, for example. The reconfiguration for the Cyclotron-Stopper magnets includes a new electronic counter for the length of wire and number of turns, as well as the actual aluminum winding forms, which were machined in house.
Each coil will weigh 700 pounds. The magnets will be made from 1.25mm x 2.5mm formvar coated superconducting wire, wet wound with Stycast epoxy with .003-inches of fiberglass between layers. There will be 57 layers with 31 turns per layer, which requires around 45,000 feet of superconducting wire per coil. The magnet will have an electrical current of 200 amps and produce a 2 Tesla field (about 20,000 times the earth’s magnetic field). Heating the whole coil in a firebrick oven for four hours at 200 degrees Fahrenheit will cure the epoxy. Once work begins, it will take about two weeks to wind each coil, including all of the prep work and curing.
The U.S. Department of Energy Office of Science (DOE-SC) Office of Project Assessment conducted a review of the FRIB Project this week, April 24-26. Charged by the Office of Nuclear Physics, the review committee assessed all aspects of the FRIB Project – technical, cost, schedule, management, environment, safety, health, and quality assurance. All charge questions to the committee were answered affirmatively at the review closeout session.
The successful review confirms FRIB is ready to establish a project baseline for cost, scope, and schedule, and is ready to begin construction of conventional facilities pending approval from the Department of Energy.
The review committee was led by Daniel Lehman, Director of the Office of Project Assessment, and included subject matter experts from the U.S. Department of Energy Office of Science, Argonne National Laboratory, Brookhaven National Laboratory, Fermi National Accelerator Laboratory, Lawrence Berkeley National Laboratory, Oak Ridge National Laboratory, SLAC National Accelerator Laboratory, and Thomas Jefferson National Accelerator Facility.
The committee will submit an official report in the coming weeks.
Welding of the helium vacuum vessel on the ReA3 beta=0.085 cavities.
After the cavity development was successfully completed over the past year, the SRF department’s effort has shifted to refurbish the remaining nine beta=0.085 cavities for the reaccelerator project. In the R&D phase, two prototype cavities already were completed, during which the fabrication steps including stack up, machining, frequency tuning, and welding procedures were defined. These two units will be used as spares and R&D cavities for further developments. From the remaining cavities, eight QWR, beta-0.085 cavities will be used in the third cryomodule. The ninth cavity will be used as a buncher cavity to match the beam from ReA3 to the next section of the linac. The ReA6 cryomodule will be installed in 2014.
The first four cavities have been completed to the “naked” cavity stage and are now being jacketed with their titanium helium vessels. The first cavity was completed this week, including a successful cold-shock, leak test. The titanium vessels are welded in-house, utilizing techniques gained during a technology transfer program with Jefferson Laboratory earlier this year. The next cavities, 5 through 8, will be electron-beam welded this week and sequenced into helium vessel fabrication after completing a round of room temperature measurements.
In parallel to the fabrication of the cavities, fabrication of the cryomodule vacuum vessel is in full swing. Welding of the vacuum vessel will be completed this month. The top flange, which contains all the instrumentation ports and the cryogenic distribution for the cryomodule, is in the final design process. In preparation of the cryomodule assembly, the cryomodule assembly group is prefabricating multi-layer insulation. The coldmass rail system is being completed now and will be moved into the clean room next week for the final coldmass assembly. But first, the vacuum interface between the coldmass support structure and the vacuum vessel has to be completed.
