Because the X-ray might penetrate the sample and strike the tape, the XRF spectrum of pure TtNikM2 crystal is achieved by subtracting the XRF spectrum of blank tape.
There's also something cool about Deadlight's setting, Seattle in 1986 might seem an odd choice, but there's a touch of retro chic which adds the game it's own style, while even loading screens feature an old Spectrum tape.
The samples were mounted on a sample holder with a two-sided adhesive tape, and the spectra were collected at room temperature.
The models with < 1% As were loaded into 3 mm-thick Teflon cells sealed on both sides by Kapton tape and XAFS spectra collected in fluorescence mode.
Visitors can walk past the full spectrum of tape measurers, making them grow in succession as if performing the "wave," or stand in front of one to force it to its crashing point.
At the other end of the technology spectrum is tape-based storage, which provides a low-cost if somewhat less convenient alternative to disk storage.
The Spectra Stack Tape Library is designed to provide a lower entry point to tape library storage.
One popular program for converting Spectrum files from tape is Taper; it allows connecting a cassette tape player to the line in port of a sound card, or through a simple home-built device to the parallel port of a PC.
In the last few years, a small army of physicists, archeologists, anthropologists, musicians, ethnomusicologists and craftsmen have probed these ancient wind instruments with tools, X-rays, stethoscopes, stroboscopes, tape recorders, frequency meters and spectrum analyzers.
As he wrote in an early paper on the issue which he sought to overcome, "...recording an instrument such as a piano or violin does not usefully load the tape over the whole audio spectrum, and thus high frequency noises are noticeable during reproduction".
