Methods and related systems are described for gamma-ray detection. A gamma-ray detector is made depending on its properties and how those properties are affected by the data analysis. Desirable properties for a downhole detector include; high temperature operation, reliable/robust packaging, good resolution, high countrate capability, high density, high Z, low radioactive background, low neutron cross-section, high light output, single decay time, efficiency, linearity, size availability, etc. Since no single detector has the optimum of all these properties, a downhole tool design preferably picks the best combination of these in existing detectors, which will optimize the performance of the measurement in the required environment and live with the remaining non-optimum properties. A preferable detector choice is one where the required measurement precision (logging speed) is obtained for all of the required inelastic elements and/or minimization of unwanted background signals that complicate the data analysis.

One of the largest fireworks displays in the Midwest will not take place this year due to coronavirus concerns.

Award-winning composer Peter McConnell is no stranger to the world of Plants vs. Zombies . Battle for Neighborville is his third soundtrack for the series. He's also no stranger to the banjo! He's been playing since he was 13, but when he spied a gorgeous 1928 Gibson five-string in a music store he regularly haunts, he knew it would be perfect for the Cheese Mines levels in the game. Peter gave the whole soundtrack a real roots feel, also using a slide guitar. He even wrote his own, in his words, "earnest" folk song, Where Have All the Plants Gone , inspired by legendary folksinger Joan Baez, who's actually a neighbor. Because Plants vs. Zombies Battle for Neighborville is a science fiction game at heart, Peter also added plenty of classic synths. He says the developers at Pop Cap also suggested the sound of the score for The Time Machine, based on the novel by H.G. Wells. Peter says getting the right emotion in his music for a game keeps the writing interesting, whether it's the
