Digital Control of Bevatron External-Proton-Beam Transport Magnets

A New Precision Measurement System for Beam Transport Type Magnets*

Comparison of cone beam computed tomography and digital radiography in detection of pulpal exposure in external cervical root resorption

Background and Aims: Pulpal exposures originated from the external cervical root resorptions have major effects on the treatment and prognosis. Therefore, the aim of this study was performed to compare the two different imaging systems-digital radiography with PSP (Photostimulable Phosphor) sensor in three horizontal different views and CBCT (cone beam computed tomography) images to assess the ...

Beam Dynamics Simulations for the Laser Proton Injector Transport Line

The recent development in the field of "laser acceleration of protons and ions" has initiated several investigations of this concept of an innovative and compact accelerator. Unique features of the Laser Ion Source (LIS) are extremely high beam current and very low transverse and longitudinal beam emittances. A general disadvantage of the LIS is a huge spectrum of the proton energies. A simulat...

SU-E-J-63: Feasibility Study of Proton Digital Tomosynthesis in Proton Beam Therapy.

PURPOSE We investigated the feasibility of proton tomosynthesis as daily positioning of patients and compared the results with photon tomosynthesis as an alternative to conventional portal imaging or on-board cone-beam computed tomography. METHODS Dedicated photon-like proton beam using the passively scattered proton beams by the cyclotron was generated for proton imaging. The eleven projecti...

Proton Transport and pH Control in Fungi.

Despite diverse and changing extracellular environments, fungi maintain a relatively constant cytosolic pH and numerous organelles of distinct lumenal pH. Key players in fungal pH control are V-ATPases and the P-type proton pump Pma1. These two proton pumps act in concert with a large array of other transporters and are highly regulated. The activities of Pma1 and the V-ATPase are coordinated u...
