Radiation measurements in the North arc: November 1986 through April 1987

This paper is an effort to share preliminary data on radiation measurements. Measurements were made using passive lithium-flouride thermoluminescent dosimeters (TLD) placed in the North arc during the start-up period of the Stanford Linear Collider (SLC). Li-7 dosimeters were used for ionizing radiation measurements, and Li-6 dosimeters moderated by polyethylene were used for measuring neutrons. In addition, some measurements were made near alcove N-6 using a Cs-137 gamma-ray source in order to determine the effectiveness of the 2 inch lead wall placed at the entrance to the alcove. When it became apparent that significant doses were being recorded at some alcoves, Pb walls were put in front of those electronic racks and Pb was put in the magnets. The Pb (approximately 1/2 inch square) in the magnet gaps was placed only on those magnets where the gap faces the aisle, and typically was put on four such magnets upbeam of each alcove and three such magnets downbeam of the alcoves. Vertical profiles were made on the photon dose at the entrance to alcove N-3 before and after the Pb was added to the magnets. Measurements were also made in front of and behind the 2 inch thick Pb wall. In …

New possibilities for exotic hadrons (open access)

New possibilities for exotic hadrons

New theoretical ideas and experimental evidence for exotic hadrons are presented. A new exciting candidate is an anticharmed baryon; i.e., a bound state of a nucleon and an F (now called D3). New experimental evidence for four-quark exotic mesons presented at this conference is discussed. The confusion in the E-iota region and the pseudoscalar spectrum still await further experimental clarification.

Texas Register, Volume 12, Number 35, Pages 1527-1550, May 12, 1987

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 Information published in the Texas Register includes proposed, adopted, withdrawn and emergency rule actions, notices of state agency review of agency rules, governor's appointments, attorney general opinions, and miscellaneous documents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.
