AI Thread Summary
The discussion centers on the difficulty of finding smaller SHV connectors suitable for Hamamatsu R6233HA photomultiplier tubes, which require a connection to a high voltage source. The user, Herbert Graaves, notes that available options are predominantly larger connectors, specifically 0.56 inches in diameter, while the needed wires are only 0.110 inches. Despite searching various electronic supply websites like Newark and Digi-Key, he has not found suitable alternatives. He expresses a preference to avoid using other types of high voltage connectors, such as Limo connectors. The thread seeks advice from others who may have faced similar challenges with Hamamatsu PMTs.

I am currently working on a project in which photomultipliers are used. Specifically, they are Hamamatsu R6233HA models. In order to test these tubes, I have to connect the wires to a high voltage source. The problem is the wires are .110 inch in diameter and are not connected at the ends, so I an trying to locate an SHV connector for the high voltage wire. However, all I can seem to find is larger SHV connectors such as those 0.56 in in diameter. I have searched Newark, Digi-Key, and other websites for smaller SHV connectors, but to no avail. Furthermore, the Hamamatsu website does not provide any helpful information in terms of what SHV connectors to use, and where to find them.

Has anyone had a similar problem before, especially if you have used the Hamamatsu PMTs in the past, and if so, where I could find smaller SHV connectors? I do not want to resort to using other high voltage connectors (i.e. Limo)if I can help it.

Thanks,

Herbert Graaves

Thread '3-terminal device external modeling'

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...

Thread 'Question about the voltage between two charged capacitors'

suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...
