The Koon shot of Operation Castle was a test of a thermonuclear device designed at the University of California Radiation Laboratory (UCRL), now Lawrence Livermore National Laboratory. The "dry" two-stage device was known as "Morgenstern" and had a highly innovative secondary stage. It was tested on April 7, 1954.
Operation Castle was a United States series of high-yield (high-energy) nuclear tests by Joint Task Force 7 (JTF-7) at Bikini Atoll beginning in March 1954. It followed Operation Upshot–Knothole and preceded Operation Teapot .
Mark 14 nuclear bomb. Castle Union was the code name given to one of the tests in the Operation Castle series of United States nuclear tests.It was the first test of the TX-14 thermonuclear weapon (initially the "emergency capability" EC-14), one of the first deployed U.S. thermonuclear bombs.
The test was part of the Koon shot of Operation Castle. The Mk-22 failed to achieve anything like its intended yield due to premature heating of the secondary from exposure to neutrons. As the other UCRL test planned for the Castle series, the liquid-fueled "Ramrod" device had the same basic design flaw, that test was canceled
Such fizzles can have very high yields, as in the case of Castle Koon, where the secondary stage of a device with a 1 megaton design fizzled, but its primary still generated a yield of 100 kilotons, and even the fizzled secondary still contributed another 10 kilotons, for a total yield of 110 kT.
Castle Bravo was the first in a series of high-yield thermonuclear weapon design tests conducted by the United States at Bikini Atoll, Marshall Islands, as part of Operation Castle. Detonated on March 1, 1954, the device remains the most powerful nuclear device ever detonated by the United States and the first lithium deuteride -fueled ...

As at 31 March 2009, the hospital had a staff force of 1201, consisting of 61 doctors, 524 nurses, 53 allied health staff and 563 other grades of staff. Its address is 15 Tsing Chung Koon Road, Tuen Mun, NT. Opened in 1961, Castle Peak Hospital is the psychiatric hospital with the longest history in Hong Kong.
