Title: Magnetized and Flat Beam Experiment at FAST

Abstract

A photocathode, immersed in solenoidal magnetic field, can produce canonical-angular-momentum (CAM) dominated or “magnetized” electron beams. Such beams have an application in electron cooling of hadron beams and can also be uncoupled to yield asymmetric-emittance (“flat”) beams. In the present paper we explore the possibilities of the flat beam generation at Fermilab’s Accelerator Science and Technology (FAST) facility. We present optimization of the beam flatness and four-dimensional transverse emittance and investigate the mapping and its limitations of the produced eigen-emittances to conventional emittances using a skew-quadrupole channel. Possible application of flat beams at the FAST facility are also discussed.

  • As an initial test of a new laser spectroscopy system placed on line to the UNISOR isotope separator, the hyperfine structure of /sup 131/Xe II and /sup 129/Xe II in their 5d /sup 4/D/sub 7/2/ and 6p /sup 4/P/sub 5/2/ levels has been investigated along with isotope shifts for /sup 128/ /sup 129/ /sup 130/ /sup 131/ /sup 134/ /sup 136/Xe relative to /sup 132/Xe. The method utilizes the resonant absorption of laser light collinear to the beam of approx. 50 keV Xe ions from the isotope separator. The spectra were produced by scanning a ring dye laser over amore » small frequency range and continuously monitoring the absorption through subsequent fluorescence of the /sup 4/P/sub 5/2/ level. Laser and other electronic drifts during the course of the measurements were small and were monitored through simultaneous absorption of a portion of the laser light in an I/sub 2/ cell. The measured hyperfine constants and isotope shifts are compared with earlier results and delta are deduced from the isotope shifts.« less

  • Intense beams with large angular momentum have important applications in electron cooling and in producing flat beams suitable for ultrafast x-ray generation, Smith-Purcell radiators, and possibly for a future linear collider. To gain a basic understanding of the influence of beam angular momentum in an otherwise space-charge-dominated beam, the behavior of such a beam in free space will be examined here, in particular, beam spreading due to space-charge force, as well as emittance oscillation. Drift space is an important part of a split photoinjector and plays a significant role in emitance compensation of a high-brightness photoinjector.
  • Compact toroids containing both toroidal and poloidal magnetic field (Spheromak-type) have been generated in CTX using a magnetized coaxial plasma gun. These CTs tear loose from the gun by magnetic field line reconnection, and they are trapped in flux conservers having various geometries. In a straight cylindrical flux conserver the CTs are observed to be unstable to a gross tilting mode. Stability to the tilting mode has been demonstrated in flux conservers having an oblate trapping region; however, the geometry of the entrance region leading to the trapping volume can also have important effects. Lifetimes of about 150 ..mu..s formore » the CTs are typically observed. Interferometric measurements give a value of about 2 x 10/sup 14/ cm/sup -3/ for the initial plasma density. The plasma temperature measured at a single spot near the minor magnetic axis decreases to around 10 eV by the time the magnetic reconnection is complete. Spectrographic measurements and pressure probe results are in agreement with this temperature. A snipper coil has been installed to induce the CT to tear loose from the gun sooner. The use of this coil is observed to speed up the magnetic field reconnection process by about a factor of 2.« less
  • This report describes an apparatus that could be used to measure both the identity and charge of an outgoing lepton in a charged current neutrino interaction. This capability in a massive detector would allow the most comprehensive set of neutrino oscillation physics measurements. By measuring the six observable transitions between initial and final state neutrinos, one would be able to measure all elements of the neutrino mixing matrix, as well as search for CP violation, and matter effects. If the measured matrix is not unitary, then one would also have an unambiguous determination of sterile neutrinos. Emulsion is considered asmore » the tracking medium, and different techniques are discussed for the application of a magnetic field.« less
