A Pickup Storage Tube

Development of a straw tube chamber with pickup-pad readout

We have developed a straw tube chamber with pickup-pad readout. The mechanism for signal pickup, the size of the pickup signal, and the distribution of signals among neighboring pads are discussed. We have tested a prototype chamber in a beam test at Brookhaven National Laboratory and have measured chamber e$ciencies in excess of 99%. ( 1999 Elsevier Science B.V. All rights reserved.

Development of Ultrahigh-sensitivity HARP Pickup Tube and Its Applications

In 1985, the author found for the first time that an experimental pickup tube with an amorphous selenium photoconductive target exhibits high sensitivity with excellent picture quality because of a continuous and stable avalanche multiplication phenomenon. We named the pickup tube with an amorphous photoconductive target operating in the avalanche-mode “HARP”: High-gain Avalanche Rushing amorph...

Human milk vitamin content after pasteurisation, storage, or tube feeding.

We investigated the effect of the composition of the storage container, Holder pasteurisation, and conditions during tube feeding on the concentration of selected vitamins in human milk. Though the fat soluble vitamins A, D, and E were not affected, the concentration of several water soluble vitamins decreased. The lower vitamin C concentration of milk stored in polypropylene containers compare...

A Broken Metallic Tracheostomy Tube

A Discussion on Interstellar Pickup Ions

Although there is a lot known about the physics that dictates the movement of the planets and starts throughout the night sky, little is known about the medium which encompasses these heavenly bodies. Let us consider our own solar system as an example of this. The reason for the orbit of planets around the Sun has been well known for quite some time. In addition to this, the predictability of t...
