MHD marking using the MSE polarimeter optics in ILW JET plasmas / Reyes Cortes, S. (IST, Lisbon (main)) ; Alper, B. (UKAEA, Culham) ; Alves, D. (CERN) ; Baruzzo, M.

(UKAEA, Culham) et al. /and JET Contributors
In this communication we propose a novel diagnostic technique, which uses the collection optics of the JET Motional Stark Effect (MSE) diagnostic, to perform polarimetry marking of observed MHD in high temperature plasma regimes. To introduce the technique, first we will present measurements of the coherence between MSE polarimeter, electron cyclotron emission, and Mirnov coil signals aiming to show the feasibility of the method.

Production of high transverse momentum particles in p-p-collisions in the central region at the CERN ISR, pt 1 / Alper, B ; Bøggild, H ; Booth, P ; Bulos, F ; Carroll, L J ; Damgaard, G ; Duff, Brian G ; Hansen, K H ; Heymann, Franz F ; Jackson, J N et al.
The inclusive production of all charged particles of transverse momentum p/sub T/ between 1.5 and 4.4 GeV/c at centre of mass angles 90 degrees and 59.4 degrees from p-p-collisions with square root s=44 and 53 GeV has been measured. No strong energy dependence is observed for these transverse momenta. [...]

Particle composition at high transverse momenta in p-p collisions in the central region at the CERN ISR / Alper, B ; Bøggild, H ; Booth, P ; Bulos, F ; Carroll, L J ; Damgaard, G ; Duff, Brian G ; Jackson, J N ; Jarlskog, G ; Klovning, A et al.
Preliminary measurements have been made at centre of mass energies square root s=31 and 44 GeV of the pi , K and p production ratios at 90 degrees for p/sub T/ between 2.0 and 3.5 GeV/c. The (K+p)/ pi ratio is given down to p/sub T/=1.4 GeV/c. [...]

Large angle production of stable particles heavier than the proton and a search for quarks at the CERN intersecting storage rings / Alper, B ; Bøggild, H ; Booth, P ; Bulos, F ; Carroll, L J ; Damgaard, G ; Duff, Brian G ; Heymann, Franz F ; Jackson, J N ; Jarlskog, G et al.
Measurements have been performed on production of particles with mass >1.5 GeV/c/sup 2/ and charge >or=2/3 for theta /sub lab/=62.5 degrees and square root s=53 GeV. At p/sub T/=0.7 GeV/c the relative rate of production of antideuterons to pi /sup -/ is (5+or-1)*10/sup -5/. [...]

Inclusive charged particle production at large angles at the CERN ISR / Alper, B ; Bøggild, H ; Booth, P ; Bulos, F ; Carroll, L J ; Damgaard, G ; Duff, Brian G ; Heymann, Franz F ; Jackson, J N ; Jarlskog, G et al.
Three different sets of results are presented: 1. Data on the inclusive production of pi /sup +or-/, K/sup +or-/, p, and p, at low transverse momenta over an angular range of 29 degrees to 90 degrees in the centre-of-mass system and for centre-of-mass energies square root s=31 and 53 GeV. [...]

Large-angle inclusive production of charged pions at the CERN ISR with transverse momenta less than 1.0 GeV/c / Alper, B ; Bøggild, H ; Booth, P ; Bulos, F ; Carroll, L J ; Damgaard, G ; Duff, Brian G ; Heymann, Franz F ; Jackson, J N ; Jarlskog, G et al.
The inclusive production of pi /sup +or-/ in proton-proton collisions has been measured for the transverse momentum range 0.15 to 1.0 GeV/c over an angular range of 29 degrees to 89 degrees in the centre-of- mass system and for centre-of-mass energies square root s=30.6 and 52.8 GeV. For each energy the invariant cross-section for fixed transverse momentum was found to increase by about 15% as the centre- of-mass rapidity decreases from 1 to 0, i.e. [...]
