Advances in Parametric-resonance Ionization Cooling

چکیده
The concept of combining ionization cooling with parametric resonances (PIC) was proposed earlier [1] in order to lead to an additional reduction of muon transverse emittances by an order of magnitude so that high luminosity in a collider can be achieved with fewer muons per bunch. After 6D cooling performed in a Helical Cooling Channel, the muon beam is injected in a channel with alternating dispersion correlated with particle free oscillations in two planes. A half integer resonance is induced in such a way that the beam becomes focused at thin wedge absorbers placed near points of zero dispersion. We discuss detuning caused by chromatic and spherical aberrations, non-linear fields, and space charge and the techniques needed to reduce the detuning, including the use of coupling resonances.

Skew-quad Parametric-resonance Ionization Cooling: Theory and Modeling
Muon beam ionization cooling is a key component for the next generation of high-luminosity muon colliders. To reach adequately high luminosity without excessively large muon intensities, it was proposed previously to combine ionization cooling with techniques using a parametric resonance (PIC). Practical implementation of PIC proposal is a subject of this report. We show that an addition of ske...
متن کاملLaser Desorption Jet-Cooling of Organic Molecules Cooling Characteristics and Detection Sensitivity
Laser desorption followed by jet-cooling allows wavelength-selective as well as massselective detection of molecules desorbed from a surface without fragmentation. The cooling characteristics and detection sensitivity of laser desorption jet-cooling of organic molecules are investigated. From the rotational contour of the electronic origin of the $1 ~-So transition of laserdesorbed anthracene, ...
متن کاملParametric study of the influence of cooling channel dimensions on PEM fuel cell thermal performance
In a polymer membrane fuel cell more than half of the chemical energy of hydrogen is converted to heat during generation of electricity. This causes an increase in the cell temperature. The Cooling field design has a significant role in cell cooling. The cell's performance and stability are reduced due to inappropriate heat dissipation. In this paper, the cooling flow and heat transfer in cooli...
متن کاملAnisotropy of optical suppression in photoassociative ionization collisions within a slow, collimated sodium atom beam
We report the observation of polarization anisotropy in the optical suppression of photoassociative ionization (PAI) collisions. Binary collisions occur within a tightly collimated and optically cooled velocity group of a single sodium beam. A laser beam, blue-detuned with respect to the atomic resonance transition, crosses the atomic beam and suppresses the PAI rate. We measure this suppressio...
متن کاملSubkelvin parametric feedback cooling of a laser-trapped nanoparticle.
We optically trap a single nanoparticle in high vacuum and cool its three spatial degrees of freedom by means of active parametric feedback. Using a single laser beam for both trapping and cooling we demonstrate a temperature compression ratio of four orders of magnitude. The absence of a clamping mechanism provides robust decoupling from the heat bath and eliminates the requirement of cryogeni...
