“…The principle and performance of the SCITIC have been reported in the previous paper. 1) The SCITIC consists of a scintillator, an optical lens, a cascade of image intensifier tubes (IIT) and a charge coupled device (CCD) camera. An image of particle tracks passing through the scintillator is focused on the photocathode of the first image intensifier tube with an optical lens system, and after amplication via three or four stages of image intensifier tubes, the track image is recorded by the CCD camera.…”

A new tracking detector, scintillating track image camera (SCITIC) was used for hyperon-scattering experiments. Since the hyperon lifetimes are short, the low-energy hyperon-nucleon scattering can be studied only with a track detector used as an active target. The present experiment has shown that the SCITIC is a promising detector for the hyperon scattering experiments. Polarized hyperons AE þ were produced through pð þ ; K þ ÞAE þ reactions with a 1.6 GeV/c pion beam on a liquid scintillator of the active target. Three sets of SCITIC were used to record the pictures of AE þ production and scattering. A kaon spectrometer was used to trigger the SCITIC with a signal of kaon from the reaction. Left/right asymmetries of the AE þ p scattering were determined through analyses of the pictorial data, and the results were in accordance with a quark-model prediction that the asymmetry was large in the AE þ p scattering while it was small in the ÃN case.

“…to measure the LS interaction in the AE þ -nucleon case. SCITIC was developed 1) and used to study hyperon-nucleon scattering experiments at KEK. 2,6) Through the experiments, SCITIC has been developed as a useful tracking detector, and the LS interaction in AE þ -nucleon was shown to be large, as expected theoretically.…”

“…In the past several years, we have developed a new trackimage detector, SCITIC, for studies spin-dependent hyperon-nucleon interactions at KEK. The principle and performance of SCITIC were reported at an earlier stage 1) and its application to hyperon-scattering experiments was discussed in a previous paper 2) together with the presentation of experimental results.…”

A new scintillation-track-image detector, SCITIC, has been developed and successfully used as an active target for hyperonscattering experiments. The principle and practical use in experiments of SCITIC have bean reported. In this paper, we present the results of a reanalysis of SCITIC data by a new method. The new method assures more precise three-dimensional (3D) track reconstruction than before by introducing a way of critically checking and an iterating data processing. After a brief presentation of the experimental setup and procedure of data taking, details of the image analysis are discussed. With the new analysis, the precision of the data for the AE þ p scattering experiment was improved leading to the conclusion that the AE þ p spin-orbit interaction is comparable to the NN interaction, and that the angular dependence of analyzing power is in good agreement with a theoretical prediction.
