Application of the HKS in the identification of kaons produced in the reaction (e, eK+)
At Jefferson Laboratory the experiment E02-017 was carried out to investigate the fission associated with kaons in the hypernuclei-producing interaction p(e,K+e')A. The newly installed high resolution kaon spectrometer (HKS) in Hall C was used as a key instrument to identify kaons. This paper introduces the HKS hardware and describes the way the kaons are identified. Maintaining most of the kaons (nearly 100%) in the data, HKS identifies kaons with a purity of 67% in this experiment. The resolution of the kaon target time reconstructed by HKS reaches 0.42 ns.
