Enrichment and radioisotope production

An apparatus comprising:

• an electron source arranged to provide an electron beam, the electron source comprising an electron injector and an accelerator;
• an undulator configured to generate a radiation beam using the electron beam;
• a molecular stream generator configured to provide a stream of molecules which is intersected by the radiation beam;
• a receptacle configured to receive molecules or ions selectively received from the stream of molecules;
• and
• a target support structure configured to hold a target upon which the electron beam is incident in use.

A method comprising:

• using an electron injector and an accelerator to provide an electron beam;
• using an undulator to generate a radiation beam using the electron beam;
• providing stream of molecules which is intersected by the radiation beam;
• selectively receiving, in a receptacle, molecules or ions from the stream of molecules which comprise a desired isotope;
• and
• directing the electron beam onto a target comprising a desired isotope to generate a radioisotope.
