“…GEM photocathodes are manufactured at Stony Brook by evaporating a ∼300 nmthick layer of CsI to their top surface using an evaporator that was on loan from INFN [12]. The evaporator was used many times in the past to evaporate photocathodes for RICH detectors used in CEBAF Hall A kaon experiments [13] and is of sufficient size to evaporate 4 HBD photocathodes simultaneously.…”

A Hadron Blind Detector (HBD) has been developed, constructed and successfully operated within the PHENIX detector at RHIC. The HBD is a Cherenkov detector operated with pure CF 4 . It has a 50 cm long radiator directly coupled in a windowless configuration to a readout element consisting of a triple GEM stack, with a CsI photocathode evaporated on the top surface of the top GEM and pad readout at the bottom of the stack. This paper gives a comprehensive account of the construction, operation and in-beam performance of the detector.

“…Throughout the experiment, the same equipment has been used in very similar kinematical conditions on C, Be, and H 2 O targets. The use of a pair of septum magnets permitted particle detection at very forward angles [14] and a Ring Imaging CHerenkov (RICH) detector [15,16,17] has been used in the hadron arm to provide an unambiguous identification of kaons when combined with the stardard particle identification apparatus of Hall A, based on aerogel Cherenkov detectors [18,19,20]. Details and motivations for the specific choices can be found in Ref.…”

An experimental study of the 16 O(e, e ′ K + ) 16 Λ N reaction has been performed at Jefferson Lab. A thin film of falling water was used as a target. This permitted a simultaneous measurement of the p(e, e ′ K + )Λ,Σ 0 exclusive reactions and a precise calibration of the energy scale. A groundstate binding energy of 13.76 ± 0.16 MeV was obtained for 16 Λ N with better precision than previous measurements on the mirror hypernucleus 16 Λ O. Precise energies have been determined for peaks arising from a Λ in s and p orbits coupled to the p 1/2 and p 3/2 hole states of the 15 N core nucleus.

The use of a pair of septum magnets permitted particle detection at very forward angles [21] and a Ring Imaging CHerenkov (RICH) detector [22][23][24][25] has been used in the hadron arm to provide an unambiguous identification of kaons when combined with the standard particle identification apparatus of Hall A, based on aerogel Cherenkov detectors [26][27][28]. In the present experiment a 92.5 mg/cm 2 solid 9 Be target with a beam current of ∼100 µA was used at a beam energy of 3775 MeV.…”

Background: In the absence of accurate data on the free two-body hyperon-nucleon interaction, the spectra of hypernuclei provides information on the details of the effective hyperon-nucleon interaction.Purpose: To obtain a high-resolution binding energy spectrum for the 9 Be(e, e ′ K + ) 9 Λ Li reaction. Method: Electroproduction of the hypernucleus 9 Λ Li has been studied for the first time with sub-MeV energy resolution in Hall A at Jefferson Lab on a 9 Be target. In order to increase the counting rate and to provide unambiguous kaon identification, two superconducting septum magnets and a Ring Imaging CHerenkov detector (RICH) were added to the Hall A standard equipment. Results: The cross section to low-lying states of 9 Λ Li is concentrated within 3 MeV of the ground state and can be fitted with four peaks. The positions of the doublets agree with theory while a disagreement could exist with respect to the relative strengths of the peaks in the doublets. The Λ separation energy, BΛ, of 8.36 ± 0.08 (stat.) ± 0.08 (syst.) MeV was measured, in agreement with an earlier experiment.
