Synchrotron radiation power calculations and bending radius choice for LER (Low Energy Ring) (open access)

Synchrotron radiation power calculations and bending radius choice for LER (Low Energy Ring)

This note will discuss ways of choosing a bending radius and synchrotron radiation absorber design. We would like to decrease the synchrotron radiation power density on the absorber's surfaces, yet we would like to reduce the LER's bending radius for better matching with the HER (beam-beam interaction criteria). We will consider two cases, both based on the PEP structure. One with 96 periods, containing 1 bending magnet per period and the other 2 bends per period. The case of synchrotron radiation absorbers outside of the bending magnet will considered also. 2 refs., 13 figs.

Texas Register, Volume 15, Number 62, Pages 4663-4733, August 17, 1990

A weekly publication, the Texas Register serves as the journal of state agency rulemaking for Texas. Information published in the Texas Register includes proposed, adopted, withdrawn and emergency rule actions, notices of state agency review of agency rules, governor's appointments, attorney general opinions, and miscellaneous documents such as requests for proposals. After adoption, these rulemaking actions are codified into the Texas Administrative Code.

Low severity coal conversion by ionic hydrogenation (open access)

Low severity coal conversion by ionic hydrogenation

The work accomplished in this project will be reported in two parts. Part one will focus on the development of catalytic ionic hydrogenation reactions utilizing a transition metal-H{sub 2} complex as the hydride donor and BF{sub 3}:H{sub 2}O as proton donor. This part reports the results of prelimiary work leading to the development of a new catalytic ionic hydrogenation system (MeCN){sub 2}PtCl{sub 2}/H{sub 2}/BF{sub 3}: H{sub 2}O. The results from some of this work have been published and the paper is included as the appendix. The second part focuses on the newly developed catalytic and other well characterized ionic hydrogenation reactions applied to lignites (Beulah-Zap), sub-bitumiuous (Wyodak), and bituminous coals (Pittsburgh {number sign}8). 19 refs., 10 tabs.

(The 25th international conference on high-energy physics at Singapore)

The traveler attended the 25th International Conference on High-Energy Physics in Singapore, August 1--8, 1990. The conference was dominated by results from the new LEP accelerator at CERN. The precision of the data from LEP is impressive, and all results are consistent with the standard model. No new physics'' has emerged at LEP. The traveler presented a talk on CERN/SPS WA80 results and had several interesting, private discussions on both L* and WA80 topics.

Progress in ETA-II magnetic field alignment using stretched wire and low energy electron beam techniques (open access)

Progress in ETA-II magnetic field alignment using stretched wire and low energy electron beam techniques

Flux line alignment of the solenoidal focus magnets used on the ETA-II linear induction accelerator is a key element leading to a reduction of beam corkscrew motion. Two techniques have been used on the ETA-II accelerator to measure and establish magnet alignment. A low energy electron beam has been used to directly map magnetic field lines, and recent work has utilized a pulsed stretched wire technique to measure magnet tilts and offsets with respect to a reference axis. This paper reports on the techniques used in the ETA-II accelerator alignment, and presents results from those measurements which show that accelerator is magnetically aligned to within {approximately}{plus minus}200 microns. 3 refs., 8 figs.
