The Physics of sPHENIX  [PDF]
Anne M. Sickles,for the PHENIX Collaboration
Physics , 2012, DOI: 10.1088/1742-6596/446/1/012050
Abstract: Jet related observables have been some of the most powerful and exciting probes for understanding the matter produced in ultra-relativistic heavy ion collisions. Full jet reconstruction was begun at RHIC, and the LHC experiments have shown the power and kinematic reach of these observables. Here we discuss the sPHENIX detector and physics program which aims to bring full calorimetric based jet reconstruction to RHIC in order to explore the temperature dependence of the strongly interacting Quark Gluon Plasma.

Physics , 2000, DOI: 10.1016/S0168-9002(99)01276-0
Abstract: The forward proton spectrometer is part of the H1 detector at the HERA collider. Protons with energies above 500 GeV and polar angles below 1 mrad can be detected by this spectrometer. The main detector components are scintillating fiber detectors read out by position-sensitive photo-multipliers. These detectors are housed in so-called Roman Pots which allow them to be moved close to the circulating proton beam. Four Roman Pot stations are located at distances between 60 m and 90 m from the interaction point.
A Very Forward Proton Spectrometer for H1  [PDF]
Pierre Van Mechelen
Physics , 2002,
Abstract: A new, very forward, proton spectrometer with large acceptance will be installed in the proton beam line of the H1 experiment in 2003. The spectrometer, located 220 m downstream of the interaction point, is based on the Roman Pot technique and consists of two stations in the cold section of the proton beam line. A brief description of this new device and expected physics results are presented.
Status of the H1 Very Forward Proton Spectrometer  [PDF]
L. Favart
Physics , 2007,
Abstract: The Very Forward Proton Spectrometer (VFPS) of the H1 experiment at HERA is collecting data since 2005. The fiber detectors in the Roman pots located at 218 and 222m downstream from the H1 interaction point, tag and measure diffractively scattered protons with a high acceptance in the $\xpom$ range [0.01, 0.025]. The experimental set up and the spectrometer tagging performance using diffractive events collected during 2006 and 2007 are discussed.

中国物理快报 , 2007,
Abstract: The precisions and its sources of spatial resolutions of tracking chambers and mass resolutions of dimuon signals in ALICE Dimuon Forward Spectrometer are explored by tracking and reconstruction of AliRoot software. The dependences of γ mass resolution on spatial resolution of tracking chambers are presented with and without background events through simulations.
The new very small angle neutron scattering spectrometer at Laboratoire Leon Brillouin  [PDF]
Sylvain Desert,Vincent Thevenot,Julian Oberdisse,Annie Brulet
Physics , 2007, DOI: 10.1107/S0021889806055257
Abstract: The design and characteristics of the new very small angle neutron scattering spectrometer under construction at the Laboratoire Leon Brillouin is described. Its goal is to extend the range of scattering vectors magnitudes towards 2x10{-4} /A. The unique feature of this new spectrometer is a high resolution two dimensional image plate detector sensitive to neutrons. The wavelength selection is achieved by a double reflection supermirror monochromator and the collimator uses a novel multibeam design.
A spin- and angle-resolving photoelectron spectrometer  [PDF]
M. H. Berntsen,P. Palmgren,M. Leandersson,A. Hahlin,J. ? hlund,B. Wannberg,M. M? nsson,O. Tjernberg
Physics , 2010, DOI: 10.1063/1.3342120
Abstract: A new type of hemispherical electron energy analyzer that permits angle and spin resolved photoelectron spectroscopy has been developed. The analyzer permits standard angle resolved spectra to be recorded with a two-dimensional detector in parallel with spin detection using a mini-Mott polarimeter. General design considerations as well as technical solutions are discussed and test results from the Au(111) surface state are presented.
The HERMES Spectrometer  [PDF]
K. Ackerstaff
Physics , 1998, DOI: 10.1016/S0168-9002(98)00769-4
Abstract: The HERMES experiment is collecting data on inclusive and semi-inclusive deep inelastic scattering of polarised positrons from polarised targets of H, D, and He. These data give information on the spin structure of the nucleon. This paper describes the forward angle spectrometer built for this purpose. The spectrometer includes numerous tracking chambers (micro-strip gas chambers, drift and proportional chambers) in front of and behind a 1.3 T.m magnetic field, as well as an extensive set of detectors for particle identification (a lead-glass calorimeter, a pre-shower detector, a transition radiation detector, and a threshold Cherenkov detector). Two of the main features of the spectrometer are its good acceptance and identification of both positrons and hadrons, in particular pions. These characteristics, together with the purity of the targets, are allowing HERMES to make unique contributions to the understanding of how the spins of the quarks contribute to the spin of the nucleon.

L. Favart
Physics , 2000,
Abstract: A new, very forward proton spectrometer (VFPS) with large acceptance is proposed to be installed in the proton beam of the H1 experiment after the luminosity upgrade in the year 2000. The spectrometer, located at 220 m downstream of the interaction point is based on the Roman Pot technique and consists of two stations situated in the cold section of the proton beam line. Physics motivations and a brief description of the proton spectrometer are presented.
Tunable VUV laser based spectrometer for Angle Resolved Photoemission Spectroscopy (ARPES)  [PDF]

Physics , 2014, DOI: 10.1063/1.4867517
Abstract: We have developed an angle-resolved photoemission spectrometer with tunable VUV laser as a photon source. The photon source is based on the fourth harmonic generation of a near IR beam from a Ti:sapphire laser pumped by a CW green laser and tunable between 5.3eV and 7eV. The most important part of the set-up is a compact, vacuum enclosed fourth harmonic generator based on KBBF crystals, grown hydrothermally in the US. This source can deliver a photon flux of over 10^14 photons/s. We demonstrate that this energy range is sufficient to measure the kz dispersion in an iron arsenic high temperature superconductor, which was previously only possible at synchrotron facilities.
