Reports

A new facility, DRAGON, designed specifically to measure radiative proton and alpha capture reaction rates involving radioactive reactants is being installed at the new ISAC accelerated radioactive beams facility. A description of the planned experimental program, specifications of the components, status of the installation (as of March 2000), and the planned schedule is provided in this report. Further, details on the gas target, the electrostatic dipole system and the detection system are also provided.

This brief report provides a summary of the status of the construction, installation and planned commissioning of the DRAGON facility. A brief summary of the first planned experiments, E824 [Measurement of the.... rate of the ²¹Na(p,γ)²²Mg reaction], E811 [A..study..¹⁹Ne(p,γ)²⁰Na reaction] and a new proposal, a study of the ²⁰Na(p,γ)²¹Mg reaction, is also included. Additional beam shifts are requested for E824.

This report provides a status report of the construction and installation of the DRAGON facility and as well provides information on what is required in terms of both stable and radioactive beams for the commissioning of DRAGON and the first planned experiment, E824, the study of ²¹Na(p,γ)²²Mg reaction. Assuming a 21Na beam intensity of 10¹⁰/s, 54 beam shifts are requested for this study.

The primary purpose of the DRAGON (Detector of Recoils And Gammas Of Nuclear reactions) facility is to measure the astrophysical S-factor or resonance strengths in radiative proton and alpha capture reactions. These reactions will be studied using inverse kinematics with gaseous targets of hydrogen or helium, and heavy ions with center of mass energies from 0.15 to 1 MeV/u. Since the facility is located at TRIUMF-ISAC, these heavy ions will consist primarily (but not exclusively) of short-lived radioactive species and the reactions are of interest to the increasing our understanding of the process of explosive nucleosynthesis in nova, supernova, and x- ray bursts. Funding for the DRAGON Facility was received April 1998 and the present plans are to initiate commissioning in the summer of 2000. The purpose of this report is to give the TRIUMF Experimental Evaluation Committee a report on the status of the building program, and the plans for the experimental program.

The vertical positions of DRAGON quadrupoles Q1 and Q2 were adjusted on November 27 and 28, 2007. This report presents the evidence that their heights were wrong, the methods used to monitor quad positions and the results of the adjustment.Those taking part in the exercise were C. Ruiz, P. Machule, C. Vockenhuber, U. Hager and the author. Valuable technical advice was given by B. Gasbarri and M. Jansz.
