10 yrs later after watching a few clips and static explanations I was still confused at a - cycle instead of + to start with, then the C3 (the next cascaded stage). Then I came across your clip (subscribed) and assumed that it'd be confusing as well, but it was not. You did explain just enough and was on the right pace to understand the whole A to Z theory mathematically, Thank you!

The most impressive Cockroft-Walton multiplier I ever saw was at Fermilab. They used it to ionize hydrogen and start the protons on their journey. The insulators were a couple meters long, at least. They used four accelerators in series back then: the C-W multiplier, a linac, the small booster ring, and then the main ring. That was almost forty years ago, so I don't know what they're using now. I imagine it's even bigger.
@AakaashNarayanan 5 ай бұрын
Hi John, I am Aakaash and I am presently a postdoc at Fermilab working on accelerator physics. The Cockroft-Walton generator at Fermilab was decommissioned in 2012 (~11 years ago) and has been replaced with a newer more modern Radio-Frequenct Quadrupole (RFQ). I was pleasantly surprised to see Fermilab mentioned in the comments. The Lab is now much more complex and diverse in terms of beam lines and experiments on site. May I know how you got to know about Fermilab (and the CW generator in it)?
@johnopalko5223 5 ай бұрын
@@AakaashNarayanan Hello, Aakaash. Thank you for the note. I was always a science geek and I loved driving around Fermilab, poking around in Wilson Hall, and taking pictures. (I would just wander in with no permission and no escort. That probably can't be done anymore.) My hobby was landscape and architectural photography and Fermilab had some wonderful buildings and sculptures. I was working as a programmer in a business setting and wanted to do something more scientific and creative with my skills. To that end, I submitted resumes to Fermilab and Bell Labs, both places I'd wanted to work since I was a teenager. I was invited to Fermilab for an interview and spent the entire day talking with people and being shown around. One of the first things they showed me was the Cockroft-Walton. If I remember correctly, my assignment would have been writing FORTRAN code to extract protons from the ring. Amazingly enough, I was offered a position at Fermilab! Almost simultaneously, I was offered a position at Bell. It was a difficult, agonizing decision but, ultimately, I decided to take the job at Bell Labs. In retrospect, it was probably the right decision, but I still feel wistful about Fermilab.

Bit old, but I love learning, and every time I find one of your videos, I do in fact learn A LOT!! thanks a million mate. I once had a very good friend in Vietnam, met him at the South East Asia Signal School, I happened to be attending the same course as he in the installation of the WACO 500 Dial phone on field wire, sort of a stupid course if you ask me, however it was a great break for me, and the course was over Christmas and New Years of 1970. (Got to see the Bob Hope SHOW!!) At any rate, we met at that course and became close friends. He was from your nation, we spent many hours after class soaking up beer and telling tales of our homelands. Although his name now escapes me, I shall always recall his face, and that Australian accent. Funny how men seem to bond when they serve together in a combat zone, even in the rear area such as Long Bien, the location of the course. For all of us attending from all over the country of South Vietnam, it was like a break in a safe area where we could relax and forget the war for a couple of weeks.
