Commissioning of the Radioactive Ion Beam Transport System for ARIEL | |
|
||
| The ARIEL facility is being commissioned to triple the availability of radioactive ion beams with ISAC at TRIUMF. The ARIEL separator and front-end facility also referred to as radioactive ion beam (RIB) transport system, connects the two new ARIEL target stations to the existing ISAC facility. The RIB transport system acts as a switchyard, in excess of 200 meters of beamlines, for delivering two additional simultaneous beams from the two ARIEL target ion sources. The primary optical building blocks of the RIB transport system are the matching, periodic, order-reversing, low-beta-insertion, dogleg, and achromatic bend sections. These blocks consist of electrostatic optical elements such as quadrupole, bender, and steerer. The first phase of the ARIEL installation is completed, and commissioning is well underway. The paper will describe the recent commissioning and early operation results of the ARIEL RIB transport system. | ||

| THPAB204 | End-to-End RMS Envelope Model of the ISAC-I Linac | 4183 |
|
||
| A full end-to-end simulation of the ISAC-I linear accelerator has been built in the first order envelope code TRANSOPTR. This enables the fast tracking of rms sizes and correlations for a 6-dimensional hyperellipsoidal beam distribution defined around a Frenet-Serret reference particle frame, for which the equations guiding envelope evolution are numerically solved through a model of the machine’s electromagnetic potentials. Further, the adopted formalism enables the direct integration of energy gain via time-dependent accelerating potentials, without resorting to transit-time factors. | ||

| THPAB205 | On-Line Retuning of ISAC Linac Beam with Quadrupole Scan Tomography | 4187 |
|
||
| The method of tomographic reconstruction has been in use at TRIUMF and elsewhere for several years, allowing for the beam diagnostic extraction of elements of the beam matrix on-line. One of the more recent applications of the technique at ISAC consists of using the measured density distribution as the input parameters for a real-time tune re-computation. This technique is advantageous since it does not require installation of dedicated emittance meters, but can instead be carried out with existing position monitors. Instead of requiring an operator to manually re-tune quadrupoles in a matching section, which can be time consuming, the technique allows for a fast and reproducible means to precisely control the beam and can be proceduralized for use by operators tuning the machine. | ||
