===================================================================
The Netherlands' National Institute for Nuclear Physics and High-Energy
Physics (NIKHEF) is searching well-qualified postdocs for experimental
work in hadronic physics. The research work will be carried out at HERMES,
the new polarized internal target set-up at DESY (Hamburg). The experimental
programme of HERMES is aimed at measurements of the spin and flavour
distributions of quarks inside the nucleon.
A successful candidate will participate in the on-going (semi-inclusive)
deep-inelastic electron scattering experiments. Special attention should
be given to the development and operation of the Vertex Chambers (a large
array of Micro-Strip Gas Chambers), for which NIKHEF is reponsible.
A significant amount of time should also be spent on the data analysis,
where the emphasis will be on the semi-inclusive data taken on various
target nuclei. As an example of the type of results that could be obtained,
we mention the envisioned studies of quark-propagation effects. By detecting
leading hadrons on various target nuclei the attenuation ratio can be measured
over a large kinematic range (in Q**2 and nu). From such measurements
quantitative information on the FORMATION TIME of hadrons can be obtained.
Up to now no such data exist.
For the second candidate the work will be aimed at the developement and
possibly construction of new detectors supplementing the existing HERMES
set-up. Recoil detectors in the backward hemisphere, for instance, could
be used to tag deep-inelastic scattering events off neutrons. Extensive
simulations have to be performed, in collaboration with other (European)
groups active in this field.
A two-year contract will be offered. One of the two positions will be
in the framework of the recently approved EC-TMR network on the
subject of 'Hadronic Physics with High Energy Electromagnetic Probes'.
For the TMR position only European nationals are egligible. Further
information can be obtained from Dr. G. van der Steenhoven, NIKHEF
(e-mail: gerard@nikhef.nl, telephone: +31 - 20 - 592 - 2145, fax: +31 -
20 - 592 - 2165). Applications should be addressed to the NIKHEF personel
department, to the attention of T. van Egdom, NIKHEF, P.O. Box 41882,
1009 DB Amsterdam, The Netherlands.
