A double-hyperfragment event has been found in a hybrid-emulsion experiment. It is identified uniquely as the sequential decay of ( 6)(LambdaLambda)He emitted from Xi(-) hyperon nuclear capture at rest. The mass and Lambda-Lambda interaction energy DeltaB(LambdaLambda) have measured for first time devoid ambiguities due to possibilities excited states. value 1.01+/-0.20(+0.18)(-0.11) MeV. This demonstrates that weakly attractive.
A hybrid experiment with nuclear emulsion and scintillating-fiber detectors (KEK-E373) has been performed to search for double-strangeness systems. Among about 10${}^{3}$ events of ${\ensuremath{\Xi}}^{\ensuremath{-}}$ hyperons captured at rest by nuclei, we have observed four which clearly show the topology cascade weak decays double-$\ensuremath{\Lambda}$ hypernuclei including ``Nagara'' event. Regarding Nagara event, values two-$\ensuremath{\Lambda}$ binding energy...
In the 2001-2002 running period of Relativistic Heavy Ion Collider (RHIC), transversely polarized protons were accelerated to 100 GeV for first time, with collisions at sqrt{s} = 200 GeV. We present results from this run single transverse spin asymmetries inclusive production neutral pions, photons and neutrons energy region 20 - forward backward angles between 0.3 mrad 2.2 respect proton direction. An asymmetry A_N (-0.090 +- 0.006 0.009) x (1.0^{+0.47}_{-0.24}) was observed neutron...
The COMET experiment aims to search for the neutrinoless conversion of a muon an electron in muonic atom. This utilizes bunched slow-extracted (bunched-SX) proton beam at 8 GeV from J-PARC main ring synchrotron. To achieve sensitivity $10^{−17}$, fraction inter-bunch stray protons, called extinction, must be less than $10^{−10}$ . commissioning with bunched-SX was performed May 2021. extinction measured by counting all secondary pions K1.8BR beamline Hadron Experimental Facility. After...
We conducted a high-power test of prototype cavity 324-MHz interdigital H-mode drift tube linac (IH-DTL) for the precise measurement muon anomalous magnetic moment ($g\ensuremath{-}2$) and electric dipole (EDM). This (short IH) was developed to verify fabrication methodology IH-DTL with monolithic structure. The electromagnetic field distribution measured compared finite element method simulation results, accuracy confirmed satisfy requirements. After 40 h conditioning, short IH stably...
A new single-sided silicon strip detector has been developed for the vertex tracker of PHENIX at Relativistic Heavy Ion Collider in Brookhaven National Laboratory (BNL). The novel "stripixel" concept by BNL Instrumentation Division was applied to first prototype sensor. feature stripixel is two-dimensional (2-D) position sensitivity with processing achieved charge sharing between two interleaved electrodes one pixel. Signals are read out projectively double layers aluminum strips. sensors...
Acceleration of positive muons from thermal energy to $100~$keV has been demonstrated. Thermal were generated by resonant multi-photon ionization muonium atoms emitted a sheet laser-ablated aerogel.

An innovative polarimeter based on proton carbon elastic scattering in the Coulomb nuclear interference (CNI) region has been installed and commissioned Blue ring of RHIC during first polarized commissioning September, 2000. The consists ultra-thin C targets four Si detectors. All elements are a 1.6 meter vacuum chamber. This paper summarizes design issues recent results.
We have carried out the experiment BNL-AGS E950 to measure analyzing power for proton-carbon elastic scattering in Coulomb-Nuclear Interference (CNI) region with a 22 GeV/c polarized proton beam. Recoil carbons from 300 keV few MeV CNI region, were detected inside AGS ring identify scattering. The preliminary results of measurement are presented.
