...came, will be noted electronically and stored on magnetic tapes. Every evening, the tapes will be sent to Cairo's Ein Shams University. There they will be fed into a computer that will calculate and memorize the point at which each recorded muon penetrated the surface of the pyramid. Because cavities within the pyramid offer less resistance to speeding muons than does solid stone, a greater number of muons will penetrate to the spark chamber along paths that take them through corridors and burial chambers. The computer will thus remember that certain well-defined areas of the pyramid...
...muon data for two months-the time necessary to get statistically valid readings-the computer will spew it all out into a cathode-ray oscilloscope. On the screen of the oscilloscope, the data will be converted into images resembling X-ray plates, one for each face of the pyramid. Chambers and corridors within the pyramid will show up as dark areas on one or more of the faces-defined by the surplus of recorded muons that penetrated these areas...
...dimensional oscilloscope images, like X rays, will show the presence of cavities but will not indicate how deep within the pyramid they...
...pinpoint their location, the scientists will move the spark chamber 35 feet away to another point within the pyramid and repeat the muon-recording process. The resulting images, combined stereoscopically with the originals, will precisely locate the hidden chambers...
Chephren's Secret. It is not by chance that the pyramid probe will begin with Cheops; most, if not all, of its chambers and corridors have been found, and scientists will be able to check the efficacy of the cosmic-ray technique by comparing their findings with known locations of cavities within the pyramid. By May, if the Alvarez technique checks out, they will move the spark chamber to the nearby Second Pyramid or Pyramid of Chephren...
