Electrical Engineering & Electronics Design

I just wanted to share the incredible news I have just received from America.

I just received news one of my pulse trigger transformer designs is now being used in one of the most expensive science experiments ever in US history.

The American company requested I design for them an extreme high voltage, high speed, high performance transformer although the application was requested as confidential.

Attached below is a comment from the company on the transformer’s performance after testing.

“The attached scope trace shows the exceptional performance of this

trigger transformer. A peak voltage of 53 kV with a rise time of 364 ns

is far superior to anything our competitors offer. The hi-pot test held

at 60 kV without breakdown, also far better than the competitors'

products. So finally, after much agony, I've authorized quantity production.”

I have attached a rise time testing result.

I have just received an email with confirmation from the client stating the final project application: section from email statement is shown below:

One of our customers is Lawrence Livermore

National Lab (LLNL) and specifically the Power Conditioning Group at the

National Ignition Facility (NIF). NIF houses the most powerful laser in

the world and is the most expensive science experiment in US history. 

The objective is thermonuclear fusion using laser ignition. This is

physics on the grand scale -- each of the two laser bays is longer than

two typical football stadiums placed end-to-end. The target chamber is

30 m in diameter.

Inside the target manipulator arm is a pulsed power system that provides

a "warm B-field" for target pre-conditioning. The attached drawing

shows a cut-away depiction including our switch, trigger generator, and

(yes) the trigger transformer that you originally designed. Each

experimental shot at NIF costs $1M (not a typo) so perhaps you can now

understand why I was so fussy about "getting it right." A system

prefire or misfire can ruin the entire experiment.

Just wanted to share the news with the community. Happy new year everyone.
