Available in PDF, EPUB and Kindle. Book excerpt: MICE superconducting spectrometer solenoids fabrication and tests are in progress now. First tests of the Spectrometer Solenoid discovered some issues which could be related to the chosen passive quench protection system. Both solenoids do not have heaters and quench propagation relied on the 'quench back' effect, cold diodes, and shunt resistors. The solenoids have very large inductances and stored energy which is 100% dissipated in the cold mass during a quench. This makes their protection a challenging task. The paper presents the quench analysis of these solenoids based on 3D FEA solution of coupled transient electromagnetic and thermal problems. The simulations used the Vector Fields QUENCH code. It is shown that in some quench scenarios, the quench propagation is relatively slow and some areas can be overheated. They describe ways of improving the solenoids quench protection in order to reduce the risk of possible failure.

Book Synopsis Preliminary Test Results for the MICE Spectrometer Superconducting Solenoids by :
Download or read book Preliminary Test Results for the MICE Spectrometer Superconducting Solenoids written by and published by . This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes the MICE spectrometer solenoids as built. Each magnet consists of five superconducting coils. Two coils are used to tune the beam going from or to the MICE spectrometer from the rest of the MICE cooling channel. Three spectrometer coils (two end coils and a long center coil) are used to create a uniform 4 T field (to ±0.3 percent) over a length of 1.0 m within a diameter of 0.3 m. The three-coil spectrometer set is connected in series. The two end coils use small power supplies to tune the uniform field region where the scintillating fiber tracker is located. This paper will present the results of the preliminary testing of the first spectrometer solenoid.

Book excerpt: I have identified two potential issues in the design of the attachments to the MICE coupling magnet cold mass. One of these attachment issues may extend into the cold mass. Both issues came to light during the analysis of what happened to the spectrometer solenoids. We must not make the same mistakes that were made on the spectrometer solenoids. The two questions that result from the identified issues are; 1) Are the superconducting low temperature superconducting leads between the coupling coil and the lower end of the high temperature superconducting (LTS) leads robust enough not quench and burn out? In the spectrometer solenoid one part of the LTS lead was not robust enough to prevent quenching and a burn out of the LTS lead and ; 2) Will there be problems with the quench protection resistors and diodes when the magnet quenches as a result of an HTS lead burning out or a disconnect of the magnet from its power supply? The second question is very important because the coupling coil has a large stored energy and inductance. As result, when current flows through the diodes and the resistors, both can be over heated. We observed resistor overheating in spectrometer magnet 2. This heating probably happened when the HTS lead the LTS lead burned out during the tests of magnet 2A and 2B respectively. (See MICE Note 324.) The answer to the first question is simple and straightforward. This is the issue that is primarily dealt with in MICE Note 324. If the resistance across the coil sub-divisions is high enough, the whole magnet will turn normal through quench-back. Making the resistance across a coil sub-division high enough is not simple.

Download or read book Fabrication, Testing and Modeling of the MICE Superconducting Spectrometer Solenoids written by and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Muon Ionization Cooling Experiment (MICE), an international collaboration sited at Rutherford Appleton Laboratory in the UK, will demonstrate ionization cooling in a section of realistic cooling channel using a muon beam. A five-coil superconducting spectrometer solenoid magnet will provide a 4 tesla uniform field region at each end of the cooling channel. Scintillating fiber trackers within the 400 mm diameter magnet bore tubes measure the emittance of the beam as it enters and exits the cooling channel. Each of the identical 3-meter long magnets incorporates a three-coil spectrometer magnet section and a two-coil section to match the solenoid uniform field into the other magnets of the MICE cooling channel. The cold mass, radiation shield and leads are currently kept cold by means of three two-stage cryocoolers and one single-stage cryocooler. Liquid helium within the cold mass is maintained by means of a re-condensation technique. After incorporating several design changes to improve the magnet cooling and reliability, the fabrication and acceptance testing of the spectrometer solenoids have proceeded. The key features of the spectrometer solenoid magnets, the development of a thermal model, the results of the recently completed tests, and the current status of the project are presented.

Book Synopsis Lessons Learned for the MICE Coupling Solenoid from the MICE Spectrometer Solenoids by :
Download or read book Lessons Learned for the MICE Coupling Solenoid from the MICE Spectrometer Solenoids written by and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Tests of the spectrometer solenoids have taught us some important lessons. The spectrometer magnet lessons learned fall into two broad categories that involve the two stages of the coolers that are used to cool the magnets. On the first spectrometer magnet, the problems were centered on the connection of the cooler 2nd-stage to the magnet cold mass. On the first test of the second spectrometer magnet, the problems were centered on the cooler 1st-stage temperature and its effect on the operation of the HTS leads. The second time the second spectrometer magnet was tested; the cooling to the cold mass was still not adequate. The cryogenic designs of the MICE and MuCOOL coupling magnets are quite different, but the lessons learned from the tests of the spectrometer magnets have affected the design of the coupling magnets.

Book excerpt: The first superconducting magnets to be installed in the muon ionization cooling experiment (MICE) will be the tracker solenoids. The tracker solenoid module is a five coil superconducting solenoid with a 400 mm diameter warm bore that is used to provide a 4 T magnetic field for the experiment tracker module. Three of the coils are used to produce a uniform field (up to 4 T with better than 1 percent uniformity) in a region that is 300 mm in diameter and 1000 mm long. The other two coils are used to match the muon beam into the MICE cooling channel. Two 2.94-meter long superconducting tracker solenoid modules have been ordered for MICE. The tracker solenoid will be cooled using two-coolers that produce 1.5 W each at 4.2 K. The magnet system is described. The decisions that drive the magnet design will be discussed in this report.
