The documents in the hands of the agency raise questions about work on how to turn uranium into bomb fuel, how to cast conventional explosives in a shape that can trigger a nuclear blast, how to make detonators, generate neutrons to spur a chain reaction, measure detonation waves and make nose-cones for missiles.
Later, in Pakistan in 2003, Babar, Khyam and Amin discussed transporting detonators back to the UK, and small radios were bought so the detonators could be hidden inside, the court heard.
Waheed Mahmood stressed that laptops and mobile phones should be disposed of on a regular basis and Khyam and Babar used code in their emails, for example "cigarettes" meant "detonators".
Its biggest snub was the denial of access to a military base at Parchin, south-east of the capital, Tehran, where the UN's nuclear watchdog, the International Atomic Energy Agency, says it may have tested detonators suitable for nuclear bombs.
It complained this week that it still had not been able to get access to Parchin, a military site where it suspects high-precision detonators designed to initiate the chain reaction for a nuclear-implosion device have been tested.
The enrichment facilities have grown in capability, capacity and number; there has been work on detonators, triggers and missile technology, too.Iran wants, at the very least, to put itself in a position where it has the expertise and materials with which to build deliverable nuclear weapons quickly.
Mr Wu said police had recently seized 178 guns, some 13,000 bullets, more than 3.5 tonnes of explosives, more than 19,000 detonators and two hand-grenades from Tibetan monasteries.
It is also thought likely to change the emphasis of the laboratory from research (in a wide range of subjects, not all of them to do with defence, let alone nuclear weapons), to the more mundane business of making the detonators of nuclear warheads.In this section A good enough performance?
A pound of plastic explosives was later discovered in the prison, along with detonators and fuses.Arnold Pickering, a murderer who fled on May 17th, was less intrepid.
But underneath, they may be frozen in indecision and internal argument about what is to happen to the guns, ammunition, explosives and detonators they have hidden around Ireland.
This "survival of the fittest" culling, which gave the scheme its nickname, quickly became less effective when the bombers came up with new and better detonators.
