Beamline 8A (BL 8A) is an undulator-based soft X-ray beamline at Pohang Accelerator Laboratory. This beamline is aimed at high-resolution ambient-pressure X-ray photoelectron spectroscopy (AP-XPS), soft X-ray absorption spectroscopy (soft-XAS) and scanning photoemission microscopy (SPEM) experiments. BL 8A has two branches, 8A1 SPEM and 8A2 AP-XPS, that share a plane undulator, the first mirror (M1) and the monochromator. The photon beam is switched between the two branches by changing the refocusing mirrors after the monochromator. The acceptance angle of M1 is kept glancing at 1.2°, and Pt is coated onto the mirrors to achieve high reflectance, which ensures a wide photon energy range (100–2000 eV) with high resolution at a photon flux of ∼1013 photons s−1. In this article, the main properties and performance of the beamline are reported, together with selected experiments performed on the new beamline and experimental system.

MAX IV is a fourth-generation, or diffraction-limited, synchrotron light source with a number of state-of-the-art beamlines. The performance of a beamline is, to a high degree, set by the energy resolution it can achieve, which in turn is governed to a large extent by the monochromator. During the design phase of a monochromator, the mechanical requirements must be fully understood and met with margin. During commissioning, the performance must be verified and optimized. In this paper, six soft X-ray monochromators at MAX IV beamlines (Bloch, Veritas, HIPPIE, SPECIES, FinEstBeAMS and SoftiMAX) are examined with a focus on their resolving power, energy range and the time required to change measurement range, as those parameters are dependent on each other. The monochromators have a modern commercial design, planned and developed in close collaboration with the vendors. This paper aims to present the current status of the commissioning at MAX IV with emphasis on elucidating the mechanical limitations on the performance of the monochromators. It contains analysis of the outcome and our approach to achieve fast and high-resolution monochromators.

The title compound, C20H36O2·CH3OH [systematic name: (3S)-4-[(S)-3-hy­droxy-3-methyl­pent-4-en-1-yl]-3,4a,8,8-tetra­methyl­deca­hydro­naphthalen-3-ol methanol monosolvate], is a methanol solvate of sclareol, a diterpene oil isolated from the medicinally important medicinal herb Salvia sclarea, commonly known as clary sage. It crystallizes in space group P1 (No. 1) with Z' = 2. The sclareol mol­ecule comprises two trans-fused cyclo­hexane rings, each having an equatorially oriented hydroxyl group, and a 3-methyl­pent-1-en-3-ol side chain. In the crystal, Os—H⋯Os, Os—H⋯Om, Om—H⋯Os and Om—H⋯Om (s = sclareol, m = methanol) hydrogen bonds connect neighboring mol­ecules into infinite [010] chains. The title compound exhibits weak anti-leishmanial activity (IC50 = 66.4 ± 1.0 µM ml−1) against standard miltefosine (IC50 = 25.8 ± 0.2 µM ml−1).

A method for reconstructing the three-dimensional grain structure from data collected with a recently introduced laboratory-based X-ray diffraction contrast tomography system is presented. Diffraction contrast patterns are recorded in Laue-focusing geometry. The diffraction geometry exposes shape information within recorded diffraction spots. In order to yield the three-dimensional crystallographic microstructure, diffraction spots are extracted and fed into a reconstruction scheme. The scheme successively traverses and refines solution space until a reasonable reconstruction is reached. This unique reconstruction approach produces results efficiently and fast for well suited samples.

Los Angeles Unified school board candidate Ref Rodriguez collected $21,000 in campaign donations from employees of his charter school network, Partnerships to Uplift Communities, in his bid to unseat incumbent Bennett Kayser in East Los Angeles’ District 5.

Most striking, a handful of his workers – a janitor, maintenance worker, tutor — are donating at or near the contribution limit, $1,100.

The contributions are a measure of supporters' high hopes to unseat Kayser in favor of Rodriguez, a candidate friendly to charter schools.

Rodriguez, an charter school administrator at Partnerships to Uplift Communities, received most of his financial support from the California Charter School Association Advocates, which received donations from such wealthy donors as former New York Mayor Michael Bloomberg and philanthropist Eli Broad.

Kayser, a former teacher elected as a board member in 2011, collected his largest donations from labor unions, particularly the United Teachers Los Angeles. 

Most of the money working toward Kayser and Rodriguez's reelection are not funneled into their individual campaigns, but to independent expenditure committees which are not subject to the $1,100 contribution limit.

In her first foray into political giving, Luz Maria Lopez, an office worker, donated $1,000 donation to the Rodriguez campaign, twice the amount of Partnerships to Uplift Communities' CEO, Jacqueline Elliot.

“I really believe in Ref. My kids go to PUC schools,” said Lopez, who has been employed by PUC since it opened 15 years ago.  

The employee contributions weren't coerced and will not be reimbursed, Rodriguez said. Many of them can be traced back to a holiday break fundraiser at Rodriguez’s sister’s home in La Puente.

“I know for many of them this is a tremendous sacrifice,” he said. “It’s just been sort of an outpouring of folks belief in me and what we are trying to do for the city.”

Charter school groups major funders

Direct campaign donations from individual contributors, such as Rodriguez’ employees, make up 18 percent of the money spent in the LAUSD’s District 5 school board race. 

The biggest donor is charter school advocacy groups, such as the California Charter School Association Advocates.

Donations have also come from self-described education reform groups that support charter school expansion and firing teachers deemed ineffective, among other issues.

All told, the advocacy groups contributed more than $700,000 to activities in support of Rodriguez and working against Kayser.

On the other side, UTLA funneled $330,000 of members’ contributions to activities supporting Kayser and working against Rodriguez.

While UTLA has turned up its political spending in the board race to stay competitive, it is routinely outspent, said Oraiu Amoni, the union’s political director.

“We never are going to be able to match [reformers] dollar for dollar,” Amoni said. “So our biggest thing is making sure our members are educated, are engaged, are aware — and vote.”

So far, campaigns and committees have spent more than $2 million on the 13 Los Angeles Unified school board candidates, according to filings with the L.A. City Ethics Commission. The contributions have paid for mailing of glossy ads, phone banks, billboards, robocalls and commercials on Spanish-language radio. 

Total contributions are expected to increase in the few days remaining before the primary and swell again in any May runoff. 

Even in major races, aggressive campaigns fueled by growing contributions from special interest groups make it difficult for candidates not affiliated with interest groups to stay competitive.

Limitless independent expenditures are "playing a major role in smaller and local elections,” said Ryan Brinkerhoff, campaign manager for Andrew Thomas, the unaffiliated candidate in the District 5 race.

Thomas, a professor at Walden University, donated $51,000 to his campaign, making him his own biggest contributor. He’s also attracted sizable local support: about 70 percent of his campaign donations come from residents who live in District 5.

Thomas has received no contributions from political action committees or advocacy groups.

Can he win?

“I think so, but it’s getting harder and harder,” Brinkerhoff said. “The results of this election are going to be very telling.”

Outside contributors, local concerns

When public schools were created in the United States, local communities were given control over their governance. Outside money “undermines the relationship between community members and their local public institutions,” according to John Rogers, an education professor at UCLA. 

“It undermines their sense that they own those institutions, and those institutions are theirs to be shaped,” he said.

Without the funds from Broad, Bloomberg and other large donors, Rodriguez’s employees’ contributions would have made up more than 30 percent of his campaign support. Instead, it’s 4 percent.

Kayser has also received support from outside the district, including donations from the American Federation of Teachers and the California Teachers Association.

"The voters have an interest in open and transparent elections in which outside dollars don't have too large an influence," Rogers said.

Clarification: This article has been updated to make clear that the California Charter Schools Association does not support or advocate for teacher firing policies. Support for incumbent Kayser from outside the district has also been noted.
