In-trap decay spectroscopy with the TITAN facility at TRIUMF
نویسندگان
چکیده
A novel in-trap decay spectroscopy facility has been developed and constructed for use with TRIUMF’s Ion Trap for Atomic and Nuclear science (TITAN). This apparatus consists of an open-access spectroscopy ion-trap, which is surrounded radially with up to seven low-energy planar Si(Li) detectors. The ion-trap environment allows for the detection of low-energy photons by providing backing-free storage of the radioactive ions, while guiding decay particles from the trap center via the strong (up to 6 T) magnetic field. Excellent ion confinement is also facilitated by the use of an intense electron beam which provides storage times of minutes or more without ion loss. These advantages, along with careful monitoring and control, provide a significant increase in sensitivity for the detection of X-rays from the electron-capture process. The design, development, and commissioning of this apparatus are presented and the future of the device and experimental technique are discussed.

A Cooler Ion Trap for the TITAN On-line Trapping Facility at TRIUMF
We present simulations of electron and proton cooling of highly charged ions in a Penning trap, including the potentially detrimental effects of radiative, dielectronic, and three-body recombination in electron cooling. We show a preliminary design for a cooler trap accommodating both electron and proton cooling, which will be a component of the TITAN ion-trap facility under construction at TRI...
متن کاملFirst use of high charge states for mass measurements of short-lived nuclides in a Penning trap.
Penning trap mass measurements of short-lived nuclides have been performed for the first time with highly charged ions, using the TITAN facility at TRIUMF. Compared to singly charged ions, this provides an improvement in experimental precision that scales with the charge state q. Neutron-deficient Rb isotopes have been charge bred in an electron beam ion trap to q=8-12+ prior to injection into ...

The TRIUMF/ISAC Control system utilizes EPICS based on VME hardware with CANbus as the fieldbus. The Electronics Development group at TRIUMF/ISAC has previously developed VME modules [1] for the ISAC facility. This success led to development of several purpose built modules. Specifically for TITAN (TRIUMF’s Ion Trap for Atomic and Nuclear science) five VME modules were developed: a frequency ge...
متن کاملβ Decay using Atom and Ion Traps
Recent advances in the techniques of atom and ion trapping have opened up a new vista in precision β decay studies due to the near-textbook source they provide: very cold (. 1 mK) and localized (. 1 cm), with an open geometry where the daughter particles escape with negligible distortions to their momenta. Atom traps: Magneto-optical traps (MOTs) have demonstrated the ability to measure the ang...
متن کاملCommissioning of the Francium Trapping Facility at TRIUMF
We report on the successful commissioning of the Francium Trapping Facility at TRIUMF. Large laser-cooled samples of francium are produced from a francium ion beam delivered by the ISAC radioactive ion beam facility. The ion beam is neutralized on an yttrium foil, which is subsequently heated to transfer the atoms into the magneto-optical trapping region. We have successfully trapped 207Fr, 209...
