Barrier RF Stacking

A novel wideband RF system, nicknamed the barrier RF, has been designed, fabricated and installed in the Fermilab Main Injector. The cavity is made of seven Finemet cores, and the modulator made of two bipolar high-voltage fast solid-state switches. The system can deliver ±7 kV square pulses at 90 kHz. The main application is to stack two proton batches injected from the Booster and squeeze them into the size of one so that the bunch intensity can be doubled. High intensity beams have been successfully stacked and accelerated to 120 GeV with small losses. The problem of large longitudinal emittance growth is the focus of the present study. An upgraded system with two barrier RF cavities for continuous stacking is under construction. This work is part of the US-Japan collaborative agreement

The Supreme Court and Fundamental Rights--A Problem of Judicial Method

Since the Constitution is a plan of written but flexible basic rights, interpreted and applied by a judiciary with few limitations upon its powers, it is necessary to avoid conferring carte blanche discretion upon the Court. This Note adopts the premises that we may be arriving at an era when liberty will demand constitutional protection of human interests other than those explicitly embodied within the text of the Bill of Rights; that judicial identification of those interests is often the most effective method for granting this protection; and that the function of constitutional due process is to preserve the relevancy of liberty to the needs of modern people. This Note will explore the Supreme Court\u27s past attempts to bring content to due process liberty, and will illustrate the difficulties in granting constitutional status to a nonconstitutional interest by tracing the legal development of one such interest, privacy. Finally, the Note will argue for a judicial methodology through which fundamental nonconstitutional interests might gain constitutional status

P2X receptors: epithelial ion channels and regulators of salt and water transport.

When the results from electrophysiological studies of renal epithelial cells are combined with data from in vivo tubule microperfusion experiments and immunohistochemical surveys of the nephron, the accumulated evidence suggests that ATP-gated ion channels, P2X receptors, play a specialized role in the regulation of ion and water movement across the renal tubule and are integral to electrolyte and fluid homeostasis. In this short review, we discuss the concept of P2X receptors as regulators of salt and water salvage pathways, as well as acknowledging their accepted role as ATP-gated ion channels
