To fill this gap, ASSAP member Dr Jason Braithwaite designed MADS (Magnetic Anomaly Detection System) specifically to record relevant magnetic fields to see if they occur in allegedly haunted locations.
helped fund this relatively expensive equipment.
Laboratory experiments have demonstrated a particular kind of low-frequency magnetic field that is capable of inducing hallucinations.
calls them EIFs
- Experience-Inducing Fields.
Broadly speaking, they are defined in the table below.
The haunting at the castle has been continuously investigated by Jason
for well over a decade.
Tourists often stay overnight on organised 'ghost sits' in the TR hoping to experience something, though it is now possible to join Jason
on a limited series of serious investigations he
runs every year that are also open to the public.
On 31 March 2004, just after the completion of the successful Muncaster Conference, Jason
and Ian Topham put MADS through its paces for the first time in the TR.
These resulted in a paper (Braithwaite, 2004), the first study ever published of time-linked synchronised magnetic measurements at a haunted location.
More experiments took place on 26 and 27 October 2004, with Jason
and Maurice Townsend the researchers present.
