We installed a source for ultracold neutrons at new, dedicated spallation target TRIUMF. The was originally developed in Japan and uses superfluid-helium converter cooled to 0.9$\,$K. During an extensive test campaign November 2017, we extracted up 325000 after one-minute irradiation of the target, over three times more than previously achieved with this source. corresponding ultracold-neutron density whole production guide volume is 5.3$\,$cm$^{-3}$. storage lifetime initially 37$\,$s...
A fast-switching, high-repetition-rate magnet and power supply have been developed for operated at TRIUMF, to deliver a proton beam the new ultracold neutron (UCN) facility. The facility possesses unique operational requirements: time-averaged current of 40~$\mu$A with ability switch on or off several minutes. These requirements are in conflict typical operation mode TRIUMF cyclotron which delivers nearly continuous multiple users. To enable creation UCN facility, beam-sharing arrangement...
This study was undertaken to determine whether satisfactory sterility without mortality could be induced in Anthonomus grandis Boheman. Adult boll weevils irradiated with 2.5 had of X-rays and immersed a 1.0% solution apholate within 8 hours greater cumulative percentage at 3 weeks than when the 2 treatments were separated by several days. However, failed destroy completely germarium all males. Destruction occurred more frequently if males still soft bodied they immersed. Thus, 2-day-old...
We report the performance of a magnetically silent optically pumped cesium magnetometer with statistical sensitivity 3.9 pT and stability 90 fT over 150 seconds measurement. Optical pumping coherent, linearly-polarized, resonant light leads to relatively long-lived polarized ground state vapour contained in measurement cell. The precesses at its Larmor frequency magnetic field be measured. Nonlinear magneto-optical rotation then plane polarization linearly probe laser beam. angle is...

The TRIUMF Ultra-Cold Advanced Neutron (TUCAN) collaboration aims at a precision neutron electric dipole moment (nEDM) measurement with an uncertainty of 10 -27 e•cm, which is orderof-magnitude better than the current nEDM upper limit and enables us to test Supersymmetry.To achieve this precision, we are developing new high-intensity ultracold (UCN) source using super-thermal UCN production in superfluid helium (He-II) spectrometer.The development status them reported article.
