Drift chamber with a c-shaped frame
J. Smyrski, Ch. Kolf, H. -H. Adam +26
We present the construction of a planar drift chamber with wires stretched between two arms of a c-shaped aluminium frame. The special shape of the frame allows to extendthe moment…
Monitoring of the accelerator beam distributions for internal target facilities
P. Moskal, H. -H. Adam, A. Budzanowski +19
We describe a direct method for monitoring the geometrical dimensions of a synchrotron beam at the target position for internal target installations. The method allows for the obse…
Low-Energy $Î-\p$ Scattering Parameters from the Reaction
J. T. Balewski, A. Budzanowski, C. Goodman +21
Constraints on the spin-averaged scattering length and effective range have been obtained from measurements of the reaction close to the production threshold b…
Study of the eta-proton interaction via the reaction p p --> p p eta
P. Moskal, H. H. Adam, A. Budzanowski +23
A measurement of the pp --> p p eta reaction at the excess energy of Q = 15.5 +- 0.4 MeV has been carried out at the internal beam facility COSY-11 with an integrated luminosity of…
Total Cross Section of the Reaction pp \to pK^+ÎClose to Threshold
J. T. Balewski, A. Budzanowski, H. Dombrowski +31
The energy dependence of the total cross section for the pp \to pK^+Îreaction was measured in the threshold region covering the excess energy range up to 7MeV. Existing model calc…
Near-Threshold eta Meson Production in Proton-Proton Collisions
J. Smyrski, P. Wuestner, A. Budzanowski +18
The production of eta mesons has been measured in the proton-proton interaction close to the reaction threshold using the COSY-11 internal facility at the cooler synchrotron COSY.…
