We present Atacama Large Millimetre Array (ALMA) 2mm continuum observations of a complete and unbiased sample 99 870micron-selected sub-millimeter galaxies (SMGs) in the Extended Chandra Deep Field South (ALESS). Our each SMG reach average sensitivities 53 microJy/beam. measure flux densities for 70 sources, which we obtain typical 870micron-to-2mm ratio 14 +/- 5. do not find redshift dependenc...

The goal of the E-823 experimental program is to measure precise half-lives and branching ratios for superallowed 0-to-0 beta emitters in mediummass (A > 60) nuclei produced by the new ISAC radioactive-beam facility at TRIUMF. This is an important adjunct to our program at the Cyclotron Institute to probe CKM unitarity via superallowed beta decay [1]. In addition to the TAMU participants, the E...

Siemens Healthcare, Knoxville, TN, USA A new positron annihilation imaging modality is described that enables nondestructive measurement of the linear attenuation coefficients (LACs) of positron beams in heterogeneous materials. This positron attenuation tomography (PAT) technique utilizes a positron emission tomography (PET) system embedded within a uniform static magnetic field, such as is fo...

Abstract Nonlinear magnetic errors in low- $$\beta$$ β insertions can have a significant impact on the beam-dynamics of collider, such as CERN Large Hadron Collider (LHC) and its luminosity upgrade (HL-LHC). Indeed, correction sextupole octupole LHC experimental has yielded clear operational benefits recent yea...

A primary goal of ATF2 (Accelerator Test Facility 2) at KEK is to demonstrate an unprecedentedly low vertical beam size at the interactateck ion point (IP) of about 37 nm. Measurements over the past years indicate that the ATF2 vertical beam size, achieved after tuning, strongly rises with bunch intensity. This increase could have several different origins. For example, it could be due to wake ...

In situ transmission electron microscopy (TEM) has been extensively applied to study radiation effects in a wide variety of materials, such as metals, ceramics and semiconductors and is an indispensable tool in obtaining a fundamental understanding of energetic beam-matter interactions, damage events, and materials' behavior under intense radiation environments. In this article, in situ TEM obs...

We have developed a technique to measure beta-delayed proton decay of proton-rich nuclei produced and separated with the MARS recoil spectrometer of Texas A&M University. The short-lived radioactive species are produced in-flight, separated, then slowed down (from about 40 MeV/u) and implanted in the middle of very thin Si detectors. The beam is pulsed and βp decay of the pure sources collected...

background: physical wedges are still widely used as beam modifiers in external beam radiotherapy. however the presence of them in the beam trace may cause beam hardening which may not be considered in many treatment planning systems. the aim of this study is to investigate the beam hardening effect generated by physical wedges via different beam quality indexes as photon spectrum, half value l...
