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)Λ.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.

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) ​​Λ. Newly established 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 certified kaons with a purity of ~ 67% in this experiment. The resolution of the kaon target time reconstructed by HKS reaches 0.42 ns.
