During the RHIC Au-run in 2001 the 200 MHz storage cavity system was used for the first time. The rebucketing procedure caused significant beam debunching in addition to amplifying debunching due to other mechanisms. At the end of a four hour store, debunched beam could account for approximately 30%-40% of the total beam intensity. Some of it will be in the abort ...

While protons are not generally associated with synchrotron radiation, they do emit visible light at high enough energies. This paper presents an overview of the use of synchrotron radiation in the Tevatron to measure transverse emittances and to monitor the amount of beam in the abort gap. The latter is necessary to ensure a clean ...

Since the RHIC Au-Au run in the year 2001 the 200 MHz cavity system was used at storage and a 28 MHz system during injection and acceleration. The rebucketing procedure potentially causes a higher debunching rate of heavy ion beams in addition to amplifying debunching due to other mechanisms. At the end of a four hour store, debunched beam can easily account for more than 50% of the total beam ...
The fill pattern in proton synchrotrons usually features an empty gap, longer than the abort kicker raise time, for machine protection. This gap is referred to as the 'abort gap' and any particles, which may accumulate in it due to injection errors and di...
This paper discusses the implementation of abort gap beam intensity monitoring at the Tevatron collider at Fermilab. There are two somewhat independent monitors which measure the intensity of the synchrotron light emitted by particles in the abort gaps. O...

Over the past several years, Fermilab has been operating with a single turn proton abort system in both the superconducting Tevatron and the conventional Main Ring. The abort kicker power supply for this system discharges a lumped capacitance into the inductive magnet load, causing the beam to enter the abort channel. The ...

The Large Hadron Collider (LHC), presently under construction at CERN, requires monitoring the parasitic charge in the 3.3ms long gap in the machine fill structure. This gap, referred to as the abort gap, corresponds to the raise time of the abort kickers magnets. Any circulating particle ...

Abortion is highly stigmatized in the United States. The consequences of stigma for abortion providers are not well understood, nor are there published accounts of tools to assess or alleviate its burdens. We designed The Providers Share Workshop to address this gap. Providers Share is a six-session workshop in which ...

The stigma surrounding abortion in the United States commonly permeates the experience of both those seeking this health service as well as those engaged in its provision. Annually there are approximately 1.2 million abortions performed in the United States; despite that existing research shows that abortion services are highly ...
The Commonwealth Regional Health Community Secretariat undertook a study in 1994 to document the magnitude of abortion complications in Commonwealth member countries. The results of the literature review component of that study, and research gaps identified as a result of the review, are presented in this article. The literature review findings indicate a ...
Unsafe abortion accounts for a significant proportion of maternal deaths, yet it is often forgotten in discussions around reducing maternal mortality. Prevention of unsafe abortion starts with prevention of unwanted pregnancies, most effectively through contraception. When unwanted pregnancies occur, provision of safe, legal abortion ...
